MMBTH34  

NPN General Purpose Amplifier  

•

This device is designed for common-emitter low noise amplifier and  

mixer applications with collector currents in the 100mA to 20mA range  

to 300MHz, and low frequency drift common-base VHF oscillator  

applications with high output levels for driving FET mixers.  

Sourced from process 47.
