MEDIUM POWER SILICON MICROWAVE TRANSISTOR
PRODUCT DATA SHEET
FEATURES:
DESCRIPTION AND APPLICATIONS:
Bipolarics' BRF480 is a high performance silicon bipolar
transistor intended for medium power linear and Class C
applications at VHF, UHF and microwave frequencies in 7.2
and 12V systems. Depending on package type, the BRF480
can operate at up to 0.5W. These applications include high
intermod receivers, CATV and instrumentation amplifiers as
well as pre-drivers, drivers and final stages in transmitter
applications such as cellular telephone. Package options in-
clude Dice, SOT-223 Surface Mount, Ceramic Micro-X,
0.145" Plastic SOT-103 and 0.230" power flange package.
