SAV-581+

Overview

The SAV-581+ is an ultra-low noise, medium current E-PHEMT transistor manufactured by Mini-Circuits. It operates within a frequency range of 0.045 to 6 GHz and utilizes enhancement mode Pseudomorphic High Electron Mobility Transistor technology. The device requires external biasing and matching components for implementation. Key electrical specifications include a typical gain of 17 dB at 2 GHz, a maximum output IP3 of +30 dBm, and a power output at 1 dB compression of +20 dBm. It functions with a single positive supply voltage.
