QO-100 Upconverter MK3 Features

The DX-Patrol QO-100 Upconverter MK3 provides precise frequency upconversion with a stable local oscillator. It has an output power of 200mW and low spurious emissions below -50dB. The unit can be locked to an internal TCXO or external GPSDO reference and has switch-selectable intermediate frequencies including 28MHz, 144MHz, 432MHz, and 1296MHz. It operates from a 10-15V supply with low current draw and compact dimensions.

Table 1. IF frequencies options

External 10MHz reference:

-Remove JP2 Off (this jumpers turns OFF the TCXO; this avoid any dual reference signal on input resulting in
erratic output signal.)
-Swap JP1 from Internal position, to External position

• *Low IF input can increase the converter spurious emissions. Using this IF, some external
Band Pass Filters might be needed between the converter and power amplifier.
• 144Mhz and UP IFs are well recommended.
