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 components on a metallized ceramic substrate.The modules produce an output power of 1.2 W into a load of 50 ? with an RF drive power of 2 mW.
