RF Circuits

This is a 6m band RF power amplifier (50 MHz) with 100W output. It used with my FT-736R and drive from 10W for the 6m SSB DX. The Building information comes from Japan CQ Magazine. The Toshiba RF bipolar power transistor will be used in it.

RF Power Amplifier Schematic and PCB


Grounding
If you want to construc this rf amplifier, it's the better way if the double side PCB use for increase the grounding and current transfer. The TX power can be tune to 120W.



RF Amplifier features:

• Input Power: 10W
• Output Power: 100W
• Operating Frequency: 50-52MHz
• Operating Mode: FM- SSB
• Operating Voltage: 10-16V DC
• Operating Current: 12A DC for 100W RF output
• TX trigger:

1. Trigger by internal RF power input detection circuit.
2. Trigger by external equipment trigger output.
