Application Guide To The A3 Series Of 10 kHz - 3 MHz Impedance Matching Amplifiers

Most RF amplifiers on the market have a nominal internal impedance of 50 Ω. However, many low to mid-frequency RF applications are characterized by impedances other than 50 Ω. It is not uncommon to encounter loads varying from 10 Ω to well over 200 Ω in this region. AR RF/Microwave Instrumentation has addressed this dilemma with the introduction of the A3 series of amplifiers that can incorporate a variable output impedance to better match those applications with load impedance other than 50 Ω.
