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

  1. Module address (default address is 0, can be set);
  2. PA setting function: power amplifier switch, ALC, ATT attenuation;
  3. 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);
  4. 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;
  5. Power amplifier failure alarm: low gain alarm;
  6. Power amplifier temperature detection: the detection range includes but not limited to -40 ℃~+ 85℃, and the detection accuracy is less than ± 3℃;
  7. PA forward power detection: total power detection, modulated signal test, detection range 25~46dBm, detection accuracy less than ± 2dBm;
  8. PA reverse power detection: total power detection, modulated signal test, detection range 25~46dBm, detection accuracy less than ± 2dBm;
  9. PA input power detection: total power detection, modulation signal test, detection range -20~4dBm, detection accuracy less than ± 2dBm;
  10. LNA setting function: ATT attenuation
  11. LNA query function: ATT attenuation
