BIPMIC® – Cascadable Silicon Bipolar Amplifier
Electrostatic sensitive device.
Observe precautions for handling.
Applications
WGeneral purpose 50 gain block for narrow and broad
band IF and RF amplifiers in commercial and industrial
Wapplications. 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)
WD 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
