1 Watt RF Signal Amplifer Class C with Transistor

1Watt RF signal amplifer circuit

1Watt RF signal amplifer circuit

Regarding the circuit is a universal 1 W. RF signal class C amplifier which is ideally suited for reduce to low power FM transmitters.

The Input much be least at 100mW for achieve 1Watt output. This is recommended to enclose the amplifier in a metal case.
