HF linear amplifier board for 12V mobile/portable/QRP 1.8-30MHz All-in-one board:
- Amplifier 1.8-30MHz
- LPF 5 pole
- RX/TX switch
- Auto band decoder
Voltage: 12-16V max
Current consumption up to 10A max
RF input: 0-10W max
RF output: 0-110W max depend voltage
All modes
160-10m Band
Class AB push pull
LPF harmonics suppression:
-22dB or more on 2nd harmonic.
-43dB or more on 3rd harmonic.
