Overview
The HMC545ATR is a low-cost Single-Pole Double-Throw (SPDT) switch manufactured by Analog Devices Inc. This device is packaged in a 6-lead SOT-26 plastic package, making it ideal for general switching applications that require very low insertion loss and a small footprint. The HMC545ATR is designed to control signals from DC to 3.0 GHz, making it particularly suited for IF and RF applications such as Cellular/3G, ISM, automotive, and portable devices.
