Product Details

The HMC8114 is a 90 W, gallium nitride (GaN), monolithic microwave integrated circuit (MMIC) power amplifier (PA) module that operates between 5.8 GHz and 18 GHz, provided in an environmentally sealed chassis.

The amplifier typically provides 68 dB of small signal gain and 49.3 dBm of saturated radio frequency (RF) output power. The amplifier draws 1 kW of power from a 48 V dc supply. The RF inputs and outputs are dc blocked and matched to 50 Ω for ease of use.
