Product specification

UHF amplifier module

BGY204

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.
