Overview
The HMC784AMS8GE is a high-power Single-Pole Double-Throw (SPDT) switch designed by Analog Devices Inc. This component is housed in an 8-lead MSOPG package and is optimized for transmit-receive applications requiring very low distortion at high input signal power levels. It operates from DC to 4 GHz and is notable for its exceptional intermodulation performance, with a third-order intercept point of +60 dBm at a +5V bias. The device supports single positive supply operation from +3V to +8V and is compatible with CMOS logic families.
