BJ-300PLUS HF CB Radio Power Amplifier 3-30MHz, Max 100W FM / 150W AM / 300W SSB Linear RF Booster for CB Walkie Talkie Transceiver BJ-300

The BJ-300PLUS HF CB power amplifier is an upgraded linear RF booster designed for CB walkie talkies and mobile CB transceivers, covering full 330MHz HF shortwave frequency band. It delivers differentiated stable power output for different working modes: up to 100W for FM, 150W for AM, and peak 300W for SSB, greatly extending your communication range for trucking, off-road, ham radio and outdoor field operations.

Equipped with a thick aluminum fin heat sink plus built-in silent cooling fan, this amplifier efficiently dissipates heat to avoid overheating damage during long-hour transmitting. It adopts automatic transmit/receive switching circuit, no manual mode switching needed during use. Integrated reverse polarity, overcurrent and overload protection circuits effectively prevent burnout of your original CB radio and internal power tubes.

Standard RF input/output ports match most CB walkie talkies directly, simple wiring without complicated modification. Every unit undergoes strict full-function aging testing before shipment to guarantee consistent linear amplification with low signal distortion and clear audio output. Ideal replacement and upgrade accessory for amateur radio enthusiasts, long-haul drivers and outdoor communication users.
