2. Module interface
- The power and monitoring interface adopts the POWER-6 connector, and its pins are defined as follows:
- RF interface: SMA-50KFD
3. Monitoring function
- Module address (default address is 0, can be set);
- PA setting function: power amplifier switch, ALC, ATT attenuation;
- PA query function: module status (including power amplifier switch, output power, reverse power, module temperature, VSWR, ATT, ALC, PA input power or LNA output), alarm status (over-temperature alarm, VSWR alarm, power amplifier fault alarm);
- Over temperature alarm: the alarm threshold is + 85℃, the detected temperature exceeds + 85℃alarm, and the power amplifier is turned off at the same time, and the power amplifier is automatically turned on when +80°C;
- Power amplifier failure alarm: low gain alarm;
- Power amplifier temperature detection: the detection range includes but not limited to -40 ℃～+ 85℃, and the detection accuracy is less than ± 3℃;
- PA forward power detection: total power detection, modulated signal test, detection range 25~46dBm, detection accuracy less than ± 2dBm;
- PA reverse power detection: total power detection, modulated signal test, detection range 25~46dBm, detection accuracy less than ± 2dBm;
- PA input power detection: total power detection, modulation signal test, detection range -20~4dBm, detection accuracy less than ± 2dBm;
- LNA setting function: ATT attenuation
- LNA query function: ATT attenuation
