Upgrade Micro-PA50-3 Third Generation Portable 50W 3.5MHz-30MHz RF Shortwave Power Amplifier LPF Filter OLED Display

Upgrade Micro-PA50-3 Third Generation Portable 50W 3.5MHz-30MHz RF Shortwave Power Amplifier LPF Filter OLED Display Popis

High-speed automatic switching of LPF filters, automatically switching between the corresponding LPFs without connecting the ACC control . Four sets of fifth-order LPFs cover the entire HAM-specific shortwave communication band, from 80 meters to 10 meters.
Power and standing wave display and protection ensure reliable operation even in poor antenna conditions, preventing damage.
A wide voltage range, voltage display, and protection functions make outdoor use with lithium batteries more convenient.
Temperature display, temperature protection, and intelligent fan cooling.
Semi-plugged mode allows for semi-plugged operation even without a PTT send connection.

Supports , , and XIEGU frequency band switching protocols (requires an ACC control cable, not included).
New LPF filter combination with reduced harmonics.
Improved gain consistency, eliminating the need for frequent radio power adjustments.
Near-perfect thermal runaway management, ensuring stable operation even at operating temperatures as high as 70C.
More comprehensive thermal runaway management reduces intermodulation distortion and further improves linearity.
Independent power supply for the OLED display, further reducing interference from the OLED screen's charge pump the ADC.
