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 Ω with an RF drive power of 10 mW. QUICK REFERENCE DATA RF performance at Tmb = 25 °C.
