This document describes the features and characteristics of the HMC345LP3 microwave switch, including broadband performance, high isolation, and low insertion loss. The switch is suitable for DC - 8.0 GHz 50-Ohm or 75-Ohm systems and can be used in broadband, fiber optics, switched filter banks, and wireless applications below 8 GHz.
The HMC345LP3 is a GaAs MMIC SP4T non-reflective positive control switch designed for use in 50-Ohm or 75-Ohm systems. It operates over a broadband frequency range from DC to 8.0 GHz and features an integrated 2:4 TTL decoder to reduce required logic control lines to two. The device is housed in a low-cost 3mm x 3mm x 1mm SMT package.
