Overview
The HMC545AE is a low-cost Single-Pole Double-Throw (SPDT) switch designed by Analog Devices Inc. This device is packaged in a 6-lead SOT26 plastic package, making it ideal for general switching applications that require very low insertion loss and a compact size. The HMC545AE is particularly suited for RF and IF applications, including cellular/3G infrastructure, private mobile radio handsets, WLAN, WiMAX, WiBro, automotive telematics, and test equipment.
