BGY122A
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. 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 ponents 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 m W. QUICK REFERENCE DATA RF performance at Tmb = 25 °C.
