Dear all,

              I would like to share the RF amplifier schematic of our SB-7 Transceiver project. This is an simple RF amplifier which amplifies the 1 Volt RF to 12 to 15 watts RF Power (PEP). This circuit uses simple transistors & Mosfets. Biasing is made using a 7808 voltage regulator with 10 K POT control. Low pass filter is used in the final stage to eliminate the unwanted signals. The PCB Size is 145 X 73mm.

Regards,
R&D team.
