This is a single band power amplifier. The boltage is fed to the collector of
the transistor and the emitter is connected to the earth. The power input os
fed to the base of the transistor. The coild and capacitors following the
transistor serve to filter the output. This circuit is known as the L-PI
circuit. This is a combination of the series tuned L and the conventional PI
circuit. This circuit could be used at HF or VHF.
