UHF amplifier modules
BGY120A; BGY120B;
BGY120D
FEATURES
·Single 3.6 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 mA.
APPLICATIONS
·Hand-held transmitting equipment operating in the 824 to 849 MHz, 872 to 905 MHz and 898 to 928 MHz frequency ranges.
DESCRIPTION
The BGY120A, BGY120B, and BGY120D are three-stage UHF amplifier modules in a SOT388A package.
Each module consists of three NPN silicon planar transistor dies, mounted together with matching and bias components on a metallized ceramic substrate.
The modules produce an output power of 1.2 W into a load of 50 W with an RF drive power of 2 mW.
QUICK REFERENCE DATA
RF performance at Tmb = 25 °C.
