BROADBAND_NOISE_AMPLIFIER

Published:2009/6/28 23:02:00 Author:May | From:SeekIC

Developed for use with antenna noise bridges for measurements at 20 meters. Provides 35 to 50 dB additional gain, not entirely constant over use-ful range of 1.8 to 30 MHz. Three strong feedback loops are introduced between drivor and final amplifier Use transistors specified, because substitutions may cut overall gain by 10 to 20 dB．-A Weiss、Noise Bridge,Ham Radio，May 1974、p 71-72
