DESCRIPTION
The DB-915-12W is a common source N-Channel
enhancement-mode lateral Field-Effect RF power
amplifier designed as booster for
GSM-R applications.
The DB-915-12W is desig ned in coope ration with
Européenne de Télécommunications S.A
(www.etsa.fr), for high gain and broadband
performance operating in common source mode
at 12 V, capable of withstanding load mismatch up
to 10:1 all phases and with harmo nics lower t han
30 dBc.
