Empower RF Systems Inc of Inglewood, CA and Holbrook, NY, USA (which produces RF and microwave power amplifiers for defense, commercial and industrial applications) says that its new model 2176 is a compact high-power gallium nitride on silicon carbide (GaN-on-SiC) continuous-wave (CW) solid-state power amplifier (SSPA) producing a minimum 4kW CW and 2kW RMS at 3.6 PAR at frequencies of 1750-2120MHz.

Standing 27-inches tall, it is less than half the size of the typical legacy uplink high-power amplifiers (HPAs) 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 brings greater reliability and improved spectral purity for increased data rates.
