DESCRIPTION
The DB-900-80W is a common source N-Channel
enhancement-mode lateral Field-Effect RF power
amplifier designed for IS-54/-136 & IS-95 base
station applications.
The DB-900-80W is designed in cooperation
with Europeenne de Telecomunications S.A.
(www.etsa.rf), for high gain and broadband
performance operating in common source mode
at 26 V, capable of withstanding load mismatch
up to 10:1 all phases and with harmonics lower
than 30 dBc.
