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
QUICK REFERENCE DATA
RF performance at T
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Note
1. In order to control the mounting-base temperature, proper heatsinking of the underside of the device is required.
