CHA7455-99F/00

The CHA7455-99F is a four-stage High Power Amplifier operating between 39.5 and 42.5 GHz and providing more than 8W of saturated output power and 24% of power added efficiency. The typical power supply is 20V/290mA (quiescent current). For these supply conditions, the CHA7455-99F provides a junction temperature below 160°C, even in saturation. The circuit is manufactured on a space evaluated 0.15μm gate length GaN-on-SiC HEMT process and is available in bare die form. It is well suited for SATCOM downlink and 5G applications
