FEATURES
·4.8 V nominal supply voltage
·3.2 W output power
·Easy control of output power by DC voltage.
APPLICATIONS
·Digital cellular radio systems with Time Division Multiple Access (TDMA) operation (GSM systems) in the
880 to 915 MHz frequency range.
DESCRIPTION
The BGY204 is a four-stage UHF amplifier module in a SOT321B package. The module consists of four NPN silicon planar transistor dies mounted together with matching and bias circuit components on a metallized ceramic substrate.
