High-power amplifiers for satcom systems

25 August 2021 Telecoms, Datacoms, Wireless, IoT

Erzia Technologies, a full-service RF/microwave amplifier and integrated assembly company delivering COTS solutions for high-performance/high frequency applications, unveiled two new high-power amplifiers designed for the unique requirements of satellite communication (satcom) systems.

Operating from 27,5 GHz to 31 GHz, the ERZ-HPA-2700-3100-43 HPA uses the latest GaN technology and consistently delivers an output power of 15 W at saturation and close to 10 W with an ACPR of -30 dBc under QPSK modulation. The module measures 131 x 100 x 33 mm (LxWxH) and weighs less than 0,5 kg. Power consumption is also low at 115 W at saturation.

The ERZ-HPA-3000-3100-46 also utilises the latest in GaN technology, operating in the extended satcom Ka-band from 30 to 31 GHz. It consistently delivers an output power higher than 20 W at saturation and 10 W with an ACPR of -30 dBc under QPSK modulation. The module is 203 x 120 x 41,6 mm (LxWxH) and weighs less than 1 kg while consuming just 230 W of power at saturation.

These COTS units can be dropped into a build of an assembled microwave signal chain of a satcom system being built, or Erzia can also add up/down converters for a greater level of integration. Both these units are rugged and reliable airborne-ready GaN devices that are able to take the place of legacy TWT amplifiers formerly perceived as the only solution at these frequencies.
