5W FM AMPLIFIER

Description

synthèse rapide du RDS

This new FM Power amplifier is equiped with the Mosfet transistor: the RD06HVF1.

Combined with the BFG35 driver, only 1mW from the input is needed to obtain the 5W power output.
All the impedance networks (Input & Output) have been determined by using the softwares: Mimp.EXE & Genesys.

The output power is adjustable from 0 to 5W through the Vgs command.
A PA OFF function is available by acting on the biais current of the BFG35.

The FM amplifier is protected from the ROS by switching off the driver stage.
