Frequently Asked Questions about Coaxial Fixed Attenuators....

What are the advantages of Weinschel's fixed
attenuators?

What dB values are available besides those in the

catalog?

Weinschel low power fixed attenuators feature a

combination of advantages over other designs:*
1. Most Weinschel attenuators feature injection molded
dielectric for better center pin captivation and alignment.
Injection molded dielectric also eliminates the need for the
epoxy hole "stake" as seen in other designs. This epoxy
hole in other designs is subject to RF leakage and movement when exposed to environmental extremes and
prolonged use.

Most any dB value is available; however you should consult

your local sales representative or the factory for design availability for a particular dB value for the selected model. There
is generally an additional charge for non-catalog values.

2. Weinschel fixed attenuators have a proprietary resistor

element, fired at 950C for superior long term stability over
temperature, power and time. The attenuator element can
be trimmed for precise custom attenuation values.
3. Weinschel fixed attenuators have no solder contacts.
They feature spring loaded plunger contacts to the
resistor cards that provide expansion tolerance over wide
temperature and power ranges.
4. Weinschel fixed attenuators are made with high quality
materials and machined to very close tolerances. The
result is a design that stands up to severe environmental
and multiple matings.
5. High power designs feature special high temperature
dielectric support beads.
Does Weinschel offer high reliability fixed attenuators?
Yes. Weinschel Corporation is a major QPL supplier of MILA-3933, CLASS III/IV, N/S Fixed
Attenuators. Most Weinschel Coaxial
Fixed Attenuators can be supplied
according to customer specified testing, environmental or military or
government specification requirements.
Hi-Rel units can be laser-marked and are manufactured from
materials which have a TML of less than 1% and CVCM less
than 0.1%. Refer to page 26 for more details.
What is a bidirectional and unidirectional attenuator?
All Weinschel attenuators are bidirectional unless they are
specified as unidirectional in the power rating specification.
Bidirectional means the maximum specified power can be
applied to either the input or output of the attenuator.
Unidirectional means the maximum specified power can only
be applied to the input port of the attenuator. Unidirectional
designs allow for smaller overall package sizes and reduced
costs. All our attenuators have maximum average and peak
pulse input power limits. The average power limit decreases
linearly as the ambient temperature increases. If these limits
are exceeded, burnout of the attenuator element results or
its calibration may be permanently changed. When used
within its specifications, an attenuator is an indispensable
component in measurement and system applications.

Can Weinschel provide attenuators for space

applications?
Yes. Weinschel fixed attenuators are being used on a wide
variety of U.S. military and commercial communication satellites. "S" level fixed attenuators can be provided for any dB
value up to 40 dB from dc to 40 GHz. Weinschel has recently introduced Model 32 (page 25) a standard SMA fixed
attenuator that operates from dc to 18 GHz and is supplied
with some of the most popular space qualified testing such
as thermal shock and peak power.
Weinschel's use of precision
connectors, injection molded captivation of connector contacts, internal
spring/plunger contacts (no solder or
contact fingers) and very precise and
stable resistors result in a superior
electrical and mechanical design that is
ideally suited for space applications.

Can Weinschel provide special fixed attenuators?

Applications....

Yes. Weinschel has produced over 2000 custom fixed attenuator designs. Specials continue to be a significant part of
Weinschel's product offering. Special features may include:

Weinschel Corporation Attenuators are used in

a wide variety of applications in the electronic
field for the control or measurement of radio
frequency energy. Attenuators are used as
accurate standards in the measurement of loss or gain by
the RF substitution method.
They are used as a means of
extending the dynamic range
of measuring equipment such
as power meters, field intensity meters, spectrum analyzers, and
amplifiers, or to prevent overloading of
receivers and amplifiers. They also reduce, by
masking, the effects of variable or mismatched impedances
on such circuit elements as oscillator, T-junctions, mixers,
etc.

Special Mounting & Environmental Conditions
Unique Test Requirements & Data

How is the temperature or power coefficient

specification applied?
These specifications tell how much the attenuation will
change when the ambient temperature or input power
changes. First multiply the catalog temperature coefficient or
power coefficient by the ambient temperature range or input
power range to which the attenuator will be exposed. Then
multiply that number by the dB value of the attenuator. The
result is the maximum change in attenuation than can be
expected over the ambient temperature range or power
range that was specified.
How is the attenuator power rating calculated?
An attenuator will handle
specified power at ambient
temperatures as specified
in the catalog. No special
fan cooling is required. At
higher temperatures the
power rating is calculated
by using catalog specifications and a straight line
graph (Example shown
above). For instance the
power rating of the Model
48 attenuator is 100 watts
to 25C and 10 watts at
10C. Using linear graph paper, plot a straight line between
these two points. This plot shows that the power rating at
75C is approximately 56 Watts.
Does Weinschel offer calibrated attenuators sets or
attenuation standards?
Weinschel offers a variety of attenuation standard sets consisting of precision designed fixed attenuators. These sets
are ideally suited for standards and research laboratories as
well as production, quality control, and inspection departments. Weinschel attenuation sets are available in either 3,
6, 10, 20 dB or 1, 3, 6, 10, 20, 30 dB attenuation values.
Each attenuator is calibrated in 1 GHz intervals to minimize
interpolation error. The calibration data is supplied in the
wooden case and is traceable to NIST. The attenuator sets
are available in stainless steel type N (Model 1 & 44), SMA,
and 3.5mm connectors. Custom sets with other connector
type and higher power sets are also available upon request.
Refer to page 63 for more details.

Fixed Attenuators can satisfy almost any requirement involving a reduction in power. Attenuators designed and
manufactured by Weinschel Corporation are very stable and
remain precision calibrated over wide ranges of humidity,
temperature, and other ambient conditions for long periods
of time.
What is Third-Order Intermodulation Distortion?
(IM3) Intermodulation distortion (IM) consists of the spurious
signals which result from the mixing of nth order frequencies
in the non-linear elements of a component. Third order
intermodulation distortion is of particular interest because
third order products typically represent the highest level
distortion appearing close to the desired signal, and as such
the highest level non-filterable distortion. Third order IM level
(IM3) is tested by injecting two pure tones of equal magnitude (f1 and f2) into the component to be tested. The third
order IM products will appear in the output spectrum at the
frequencies 2f1-f2 and 2f2-f1. These products are characterized by defining their level (in dBc) relative to the
fundamental output tones at either f1 or f2.
Does Weinschel offer any attenuators with IM3
specified?
Yes Weinschel has recently introduced new as well as
updated models specifically for applications requiring low
intermodulation distortion. New models include a series of
attenuators containing 7/16 connectors that operate over the
dc to 5 GHz frequency range. These models are available in
25, 50, 150 Watt varieties with a wide choice of dB values.
Weinschel has also modified several of its standard fixed
attenuators (24, 33, 40, 45, 46, 47, 48, 48, 53, 57, 58, & 79).
Refer to the specific data sheet for IM3 details.

Definitions & Conditions of Attenuator

Related Parameters.....

Attenuation: A general term used to denote a

decrease in magnitude in transmission from one
point to another. NOTE: it may be expressed as a
ratio, or by extension of the term, in decibels.
SWR: The ratio of voltage (or current) at a loop
(maximum) on a transmission line to the value at a
node (maximum). It is equal to the ratio of the characteristic impedance to the impedance of the load
connected to the output end of the line.
Maximum Average Power: That maximum input
power applied for a long time at the maximum
operating temperature, with output terminated in
the characteristic impedance, which will not permanently change the specifications of the attenuator
after return to 20C at 10 mW input. Rating, particularly for smaller attenuators, is influenced by
structure(s) in thermal contact with unit. Heat
sources and sinks can significantly alter the input
power handling of an attenuator.
Power Coefficient of Insertion Loss: Variation in
dB of insertion loss when input power is varied from
10 milliwatts to full rated power after steady state
condition has been reached. To obtain dB, multiply
power coefficient by dB and watts.
Maximum Peak Power: That peak power which
when applied for a specified time at the maximum
operating temperature at a pulse duration of 5
microseconds, while the output is terminated in the
characteristic impedance, will not permanently
change the specifications of the attenuator when
returned to 20C and 10 mW input.
Temperature Coefficient: Maximum change of
insertion loss in dB/C over maximum operating
temperature range. To obtain, multiply temperature
coefficient by dB and temperature change in C.

Shock and Vibration: In the three major axes, case

or body must be solidly supported when tested.
Frequency Sensitivity of Insertion Loss: Peakto-peak variation in dB when swept through the
frequency range at 20C.
Operating Temperature Limit: Maximum temperature in C at which attenuator will operate with full
input power; derating function for maximum power
vs temperature is specified if required.
Deviation of Insertion Loss from Nominal: At
20C and an input power of 10 mW at a specified
reference frequency.
Connector Life: Connected/disconnected cycles
with complete axial engagement/disengagement
without side thrust; all electric and mechanical
specifications must be complied with after specified
life cycle.
Intermodulation Distortion: Intermodulation distortion (IM) consists of the spurious signals which
result from the mixing of nth order frequencies in the
non-linear elements of a component. Third order
intermodulation distortion is of particular interest
because third order products typically represent the
highest level distortion appearing close to the
desired signal, and as such the highest level non-filterable distortion. Third order IM level (IM3) is
tested by injecting two pure tones of equal magnitude (f1 and f2) into the component to be tested.
The third order IM products will appear in the output
spectrum at the frequencies 2f1-f2 and 2f2-f1.
These products are characterized by defining their
level (in dBc) relative to the fundamental output
tones at either f1 or f2.
