HF amplifier modules
BGY148A; BGY148B
FEATURES
Single 6 V nominal supply voltage
3 W output power
Easy control of output power by DC voltage
Silicon bipolar technology
Standby current less than 100
A.
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
with an RF drive power of 10 mW.

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.
It is therefore advisable that the device is mounted on a printed-circuit board with metallized through holes.
