HamGeek Micro PA50-3 Portable 50W RF Power Amplifier 3.5-30MHz HF Power Amplifier OLED LPF + 2PCS IRFZ24N MOSFETs

HamGeek Micro PA50-3:
1. Improvements:
- New LPF filter combination with smaller harmonics.
- Better gain consistency, no need to frequently adjust radio power.
- Almost perfect thermal runaway management ensures stable operation even when the working temperature reaches 70℃.
- Based on more comprehensive thermal runaway management, intermodulation distortion is now reduced and linearity is further improved.
- Independent OLED display screen power supply, further reducing the interference of OLED screen charge pump on ADC.
- Some minor optimizations, such as power fuses, fan control, temperature sensing, etc.

2. Features:
- High speed automatic transmission and reception switching, with RF triggering, can automatically switch transmission and reception states even without PTT SEND.
- High speed automatic switching of LPF filters, without the need to connect ACC control cables, can automatically switch corresponding LPFs. Four sets of 5th order LPFs cover the entire HAM dedicated short wave communication frequency range from 80 meters to 10 meters.
- Power and standing wave display and protection ensure reliable equipment safety under poor antenna conditions and are not easily damaged.
- Wide voltage range, voltage display and protection, more convenient for outdoor use of lithium battery power supply.
- Temperature display, temperature protection, intelligent fan cooling.
- Half insertion mode function, which can have half insertion function even without connecting PTT SEND.
- Supports for ICOM, YAESU, and XIEGU band switching protocols (requires ACC control cable connection, which is not included).
