Design and build a prototype single stage Microwave power amplifier operated at 2.4 GHz with a linear region of operation up to our desired output of 1 watt or 30 dBm.
The circuit has frequency response ranging from 100Hz to 3MHz; gain is about 30dB.
Bi-directional means you can mount the amplifier at the antenna to help overcome any cable loss, and the amplifier will automatically switch between receive and transmit modes.
The basic function of a power amplifier is always the same: to boost a low-power signal to a higher power level, to be delivered to the amplifier load.
The BC547 (equiv 2N2222) can be used to build a 500mW linear amplifer covering the entire HF band with excelent spectral purity and no neutralising at all.
This is a normal cathode-grounded-bias-less amplifier.
For 160, 80 and 40 meter bands. With 58N20s it will deliver 400W on 40 and 700 on 160/80 meter band. The amp needs 25/35W of drive for full output.
No tuned elements. Does not use in resonant circuits
