鈥?Cascadable Silicon Bipolar Amplifier
Electrostatic sensitive device.
Observe precautions for handling.
Applications
General purpose 50
W
gain block for narrow and broad
band IF and RF amplifiers in commercial and industrial
applications. The 50
W
level allows directly to cascade
this amplifier with minimal external circuitry, thus pro-
viding a simple, cost effective way to achieve low level
amplification.
