Overview
The HMC545A and HMC545AE are low-cost Single-Pole Double-Throw (SPDT) switches manufactured by Analog Devices Inc. These devices are packaged in a 6-lead SOT26 plastic package and are designed for general switching applications that require very low insertion loss and a small footprint. They are particularly suited for IF and RF applications, including cellular/3G, ISM, automotive, and portable devices. The switches operate from DC to 3.0 GHz, making them ideal for filter and receiver switching in various wireless communication systems.
