2400 MHz Filtered Driver Amplifier Kits

This kit has been designed by David Bowman G0MRF and contains all the parts required to drive a PA on 2.4 GHz for QO-100. The completed board will have a gain of about 25 – 26 dB and for best linearity, should be kept to 200 mW output.

This kit can be assembled in a couple of hours by constructors with a medium level of experience. In addition to the kit you will need a 2.5mm drill for the mounting holes in the heatsink. You will also need a pair of SMD tweezers, a soldering iron with a fine tip and some small diameter solder e.g. 0.4 or 0.5mm. Finally, a headband magnifier or similar will help considerably with the SMD parts.

David suggests running the board from 12 or 12.6 volts. At 13.8 volts the supply current and power dissipation increase without any significant improvement in performance
