CTRL 1:Amplifier transmitting status, receiving off

CTRL 0:Receive status, transmitting off

• Port description:

1. "T/R_IN" port is connected to the radio frequency port of the digital radio station, and the "ANTENNA" port is connected to the antenna;

2."CTRL" is the transmission enable of the digital radio station connected in non-auto mode (auto mode and enable mode, need to be set at the factory, 3.3V TTL level);

3."DC-IN" is + 12 power supply, the welding pad pressed by this through-capacitor is the negative electrode;

4“Red indicator light”, the red indicator light is on to indicate the transmitting state, and the red indicator light is off to indicate the receiving state

• Operating temperature:-20～+75℃
• Voltage:12V
• Working current:12V/5.5A@20W；
