The NE960R5 Series are 0.5 W GaAs MES FETs designed for middle power transmitter applications for X, Kuband microwave communication systems. It is capable of delivering 0.5 watt of output power (CW) with high linear gain, high efficiency and low distortion and are suitable as driver amplifiers for our X, Ku-band NEZ Series amplifiers etc. The NE961R500 and the NE960R500 are available in chip form. The NE960R500 has a via hole source grounding and PHS (Plated Heat Sink) for superior RF performance. The NE960R575 and the NE962R575 are available in a hermetically sealed ceramic package. The NE962R575 is suitable for oscillator application. Reliability and performance uniformity are assured by NEC's stringent quality and control procedures.
