BGY122B Overview
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 mW.
