DESCRIPTION

The BGY122A and BGY122B are three-stage UHF amplifier modules in a SOT388B package. Each module consists of three NPN silicon planar transistor dies mounted together with matching and bias circuit components on a metallized ceramic substrate.

The modules produce an output power of 1.2 W into a load of 50 Ω with an RF drive power of 2 mW.

FEATURES

• Single 4.8 V nominal supply voltage

• 1.2 W output power

• Easy control of output power by DC voltage

• Very high efficiency (typ. 55%)

• Silicon bipolar technology

• Standby current less than 100 µA.

APPLICATIONS

• Hand-held transmitting equipment operating in the 824 to 849 MHz and 872 to 905 MHz frequency ranges.
