 The CHA7455-99F is a four stages High Power Amplifier operating between 39 and 43.5GHz and providing typically 9W of saturated output power and 25 % of Power Added Efficiency.The typical power supply is 20V/240mA (quiescent current). Thanks to a low drain voltage biasing, the CHA7455-99F provides a junction temperature below 160°C, even in saturation. The circuit is manufactured on a space qualified GaN-on-SiC HEMT process and is available in bare die form. It is firstly dedicated to space, military and telecom applications and well suited for a wide range of microwave applications and systems.
