DESCRIPTION
The DB-900-100W is a com mon source N-Channel enhancement-mode lateral Field-Effect RF
power amplifier designed for IS-54/-136 & IS-95
base station applications.
MECH. SPECIFICATION L=80 mm W=50 mm H=10 mm
ORDER CODE
DB-900-100W
The DB-900-100W is designed in cooperation
with Europeenne de Telecomunications S.A.
(www.etsa.rf), for high gain and broadband
performance operating in comm on source mode
at 26 V, capable of withstanding load mismatch
up to 10:1 all ph ases and with harmo nics lower
than 30 dBc.
