GENERAL DESCRIPTION
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.
