Product Overview Mini-Circuits’ ZVA-183G+ is a Class-A, four-stage, unconditionally stable amplifier providing flat gain over an extremely wide frequency range from 0.5 to 18 GHz. This model is capable of delivering up to ½W output power at Psat with low noise and high IP3 supporting a wide range of sensitive, high-dynamic range receiver applications and many systems where high performance over wideband is needed. It operates on a +15V supply and features built-in safety features including protection against reverse bias and immunity to accidental open or short loads. The amplifier comes in a rugged, compact case (4.18 x 3.36 x 3.57″) with SMA connectors and an optional heat sink for efficient cooling.
