The UPG2405T6Q compact gallium-arsenide (GaAs) monolithic microwave integrated-circuit (MMIC) single-pole triple-throw (SP3T) switch from California Eastern Laboratories targets near-field communications (NFC), RFID, Bluetooth, Wi-Fi, ZigBee/802.15.4, and other wireless applications. It can support very low frequencies down to 10 MHz to suit NFC and RFID systems while still scaling up to support higher-frequency bands for other applications. Also, its triple-throw design and low insertion loss characteristics enable it to support Bluetooth and Wi-Fi devices, even in the same module.

Such combo products are becoming more common as Wi-Fi and Bluetooth get adopted together in laptops, netbooks, printers, smart phones, and other handheld wireless devices. The switch also would fit ZigBee/802.15.4 products in automatic meter reading, wireless security, cable replacement, and lighting systems in both commercial and residential buildings. The UPG2405T6Q measures 2.0 by 1.35 by 0.4 mm, which CEL says is rare for a triple-throw switch of such high performance. This size also helps enable wireless designs with small form factors. 

Shipping now, the UPG2405T6Q costs $0.40 in lots of 100,000. Evaluation boards are available now through CEL’s sales offices as well as from Mouser Electronics.
