140 W L, S-BAND PUSH-PULL POWER GaAs MES FET

DESCRIPTION

The NES1823P-140 is a 140 W push-pull type GaAs MES FET designed for high power transmitter applications

for PCS, DCS, PHS and IMT2000 base station systems. It is capable of delivering 140 W of output power (CW) with

high linear gain, high efficiency and excellent distortion under the condition of 12 V operation. Its primary band is 1.8

to 2.3 GHz, however with different matching, 60 MHz or less of instantaneous bandwidth can be achieved anywhere

from 0.8 to 2.3 GHz. The device employs 0.9 mm Tungsten Silicide gates, via holes, plated heat sink, and silicon

dioxide passivation for superior performance, thermal characteristics, and reliability.

Reliability and performance uniformity are assured by NEC’s stringent quality and control procedures.
