QO100-20W power amplifier assembly.

Asembly instructions can be download here

This document describes the assembly of the 20W amplifier kit as designed by Rens PA3AXA. The assembly of this kit requires from the builder some soldering skills, good eyesight and a stable hand. From the tool side you need a 50W Weller soldering station with small tip, thin solder wire, tweezers, magnifiers and a smd heat gun. The flow soldering of the final stage with pcb and heat spreader is already done. This Amplifier is designed to use with an bare mixer to make SSB on QO100. Filtering inside the amplifier is good enough to use as low as 28MHz IF. If you use a Pluto as a driver be sure the output of the Pluto is adjusted at -7dBm or use a attenuator to get it.

Amplifier specifications:

  • Output power, > 43dBm
  • Gain, 50dB
  • Supply voltage 12V (ptt and driver), 26V (final stage)
  • Dimensions. lxbxh  110 x 36 x 30 mm
  • Frequency 2400-2500 MHz
