25W RF Amplifier Circuit 88-108Mhz

25W RF amplifier circuit diagram. The circuit is used for 88-108Mhz FM Transmitter. This RF amplifier use power transistor BLY88C for the final signal amplifier.

About RF Amplifier
An RF power amplifier is a type of electronic amplifier which is utilised to convert a low-power radio-frequency signal into a larger signal of significant power, usually for driving the antenna of a transmitter. It is usually optimized to have high efficiency, high output Power (P1dB) compression, good gain, good return loss on the input and output, and optimum heat dissipation.

The basic applications of the RF power amplifier include driving to another high power source, driving a transmitting antenna, microwave heating, and exciting resonant cavity structures. Among these applications, driving transmitter antennas is most well known.
More explanation about power audio amplifier can be found at wikipedia.org
This is a demonstration about 01A RF Amplifier which is build used old tube component to amplify the signal.
