BIPMIC^® – Cascadable Silicon Bipolar Amplifier
Electrostatic sensitive device.
Observe precautions for handling.
Applications
W General purpose 50 gain block for narrow and broad
band IF and RF amplifiers in commercial and industrial
W applications. The 50 level allows directly to cascade
this amplifier with minimal external circuitry, thus pro-
viding a simple, cost effective way to achieve low level
amplification.
Features
D Broadband amplification
D Low operating voltage (6 V)
W D 50 cascadable gain block
D High gain (17.5 dB @900 MHz)
D Low noise figure (3.3 db @900 Mhz)
D Low cost surface mount plastic package
D Few external components
