Fairchild Semiconductor MMBTH34 Datasheet

MMBTH34 Surface Mount NPN RF-IF Amp

General Description

This device was designed for common-emitter low noise
amplifier and mixer applications in the 100 mAto15mA
range to 300 MHz, and low frequency drift common-base
VHF oscillator applications with high output levels for driving
FET mixers.
