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 mA.
APPLICATIONS
·Portable communication equipment operating in the 400 to 440 MHz and 430 to 488 MHz frequency ranges respectively.
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 W with an RF power of 10 mW.
QUICK REFERENCE DATA
RF performance at Tmb = 25 °C.
