Compact High Power GaN on SiC Solid State CW Amplifier: 2176

January 31, 2020

Empower's model 2176 is a compact high power GaN on SiC solid state CW amplifier. Standing 27 inches tall, it's less than half the size of the typical legacy uplink HPA's that it replaces. The slightly broader band brings flexibility to transmit in either of the two uplink channels. Besides the dramatic size reduction, the upgrade from legacy design to a next generation SSPA from Empower RF brings greater reliability and improved spectral purity for increased data rates.

The 2176 is based on Empower's established and field proven Next Generation architecture that is tactically deployed and operating on multiple levels in support of a variety of critical DOD missions.

The 2176 comes complete with internal directional coupler, external forward and reverse sample ports, and an easy to use web GUI. In depth health monitoring with alarms visible on the front panel are also pushed out via the LAN port. Output modes include Manual Gain Control (MGC), AGC and ALC which provide flexibility when integrating into legacy uplink systems. For critical “on air” applications, the 2176 provides "Graceful Output Power Degradation", backing down power to a safe operating level in the event of component failure or excessive Load VSWR condition.

Remote management and diagnostics are achieved via an embedded web server, a WEB API or M2M. The design allows network site management and control simply by connecting the unit's Ethernet port to a LAN. Overall system gain, modulation mode and output power can be controlled via Local GUI, Remote GUI, M2M WEB API and M2M ASCII commands. BIT down to the pallet level is included for mission critical applications.
