Application And Use Of The 350AH1 Low-Frequency Amplifier

Most RF amplifiers have what has come to be known as“standard” 50O output impedance. The AR RF/Microwave Instrumentation model 350AH1 RF amplifier is unique in that its output impedance is typically less than 1O. With such low output impedance and a broad frequency range of 10Hz to 1MHz one might mistakenly make the assumption that the 350AH1 is merely a high-end audio amplifier. This article will explore the characteristics of this unique amplifier, cover methods of interconnecting amplifiers for enhanced performance, and discuss some of the applications addressed by this robust, versatile amplifier.
