Mini-Circuits’ ZHL-10M4G21W2+ is an instrument amplifier providing more than 1W of output power with a typical small signal gain of 44dB over the 10 to 4200 MHz frequency band. The amplifier uses state-of-the-art semiconductor technology and can be used in a wide range of applications. This model features a built-in digital step attenuator on the input providing gain control from 0 to 15 dB in 1 dB steps with push-button attenuation control on the front panel. The amplifier runs on a built-in 110/220V power supply, making it easy to use in most lab environments. It features thermal self-protection, preventing damage to the amplifier and providing added reliability. It comes housed in a light-weight aluminum alloy case (15.35 x 8.27 x 3.25”) with N-type connectors, ideal for bench-top use. 2 N-male to SMA-female adapters come included for the user’s convenience.
