CHA7453-99F/00

The CHA7453-99F is a four-stage High Power Amplifier operating between 37.5 and 41.5 GHz and providing more than 8W of saturated output power and 22% of power added efficiency. The typical power supply is 20V/290mA (quiescent current). For these supply conditions, the CHA7453-99F 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.
