Amplifier
Applications Description
 CDMA2000 cellular band Skyworks SKY65170-11 is a fully-matched, 0.5 W Power
Amplifier (PA) with high efficiency, designed for use in the 860 to
 WCDMA, Band V 900 MHz band.
 Femtocell transmitters The device is fabricated using Skyworks high reliability Indium
Gallium Phosphide (InGaP) Heterojunction Bipolar Transistor (HBT)
Features technology. This process allows for single supply operation while
maintaining high efficiency and good linearity.
 Wideband frequency operation: 860 to 900 MHz The SKY65170-11 contains all of the active bias and RF matching
 High gain: > 30 dB circuits, which make it easy to integrate into 50 Ω RF systems.
 OP1dB: > +27 dBm The internal input and output match are optimized for gain, 1 dB
Compression Point (P1dB), Adjacent Channel Leakage Ratio
 ACPR ≤ –48 dB for POUT > +18 dBm (ACLR), and efficiency when integrated in a 50 Ω system.
 Single DC supply: 5 V The primary bias to the SKY65170-11 can be supplied directly
 Internal RF match and bias circuits from a single 5 VDC supply. The PA is designed to operate with
 Small footprint, MCM (20-pin, 6 x 6 mm) SMT package (MSL3, lower current by reducing the bias voltage.
260 C per JEDEC J-STD-020) The device is internally matched and mounted in a 20-pin,
6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology
Skyworks offers lead (Pb)-free RoHS (Restriction of (SMT) package, which allows for a highly manufacturable low
Hazardous Substances) compliant packaging. cost solution. The device package and pinout for the 20-pin MCM
