DESCRIPTION
The BGY148A and BGY148B are three-stage UHF amplifier modules in a SOT421A 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 3 W into a load of 50 Ω with an RF drive power of 10 mW.

FEATURES
• Single 6 V nominal supply voltage
• 3 W output power
• Easy control of output power by DC voltage
• Silicon bipolar technology
• Standby current less than 100 µA.

APPLICATIONS
• Portable communication equipment operating in the 400 to 440 MHz and 430 to 488 MHz frequency ranges respectively.
