PRELIMINARY DATA SHEET
GaAs MES FET
4W/8W C-BAND POWER GaAs FET NEZ Series
4W/8W C-BAND POWER GaAs FET
N-CHANNEL GaAs MES FET
DESCRIPTION
PACKAGE DIMENSIONS (unit: mm)
The NEZ Series of microwave power GaAs FETs offer
high output power, high gain and high efficiency at C-band
for microwave and satellite communications.
Internal input and output circuits matched to 50 Ω are
designed to provide good flatness of gain and output power
in allocated band.
To reduce the thermal resistance, the device has a PHS
(Plated Heat Sink) structure.
NEC’s strigent quality assurance and test procedures
guarantee the highest reliability and performance.
