CHA8265-98F

The CHA8265-98F from United Monolithic Semiconductors is a Triple-Stage GaN MMIC Power Amplifier (PA) that operates from 27.5 to 31 GHz. It is designed for SATCOM and 5G applications and is manufactured using a GaN-on-SiC HEMT process with an internally matched 50-ohm output. This PA delivers a saturated output power of 25 W (44 dBm) with a linear gain of 25 dB and a power-added efficiency of 30%. It has an input return loss of 10 dB and an output return loss of 8 dB. 

The CHA8265-98F requires a 25 V drain bias voltage and has a quiescent drain current of 340 mA. It is available as a bare die measuring 3.6 × 3.6 mm and can operate over a temperature range from -40°C to +85°C.
