About
The GaN Ku SSPA/BUC 325W is an outdoor unit providing 325W of output power for Ku-band SATCOM broadcast applications. It features a robust design with options for extended temperature range (-40 ºC to +55 ºC) and redundant systems (1:1, 2:1, N:1). The unit supports automatic control modes (AGC, ALC) and offers various interfaces including RF Input (N(f) for BUC / SMA(f) for SSPA), RF Output (WR75 grooved), AC Line (3-pin MIL circular), and M&C (19-pin MIL circular). Monitoring and control are available via RS-485/USB, allowing for monitoring of forward & reverse output power, input power, temperature, and summary alarms. It also includes internal self-protection mechanisms for temperature and reflected power. The power supply operates on 90-264 VAC, 50-60 Hz.
