RF switches target test and measurement, Wi-Fi, sensors, appliances, and other radio equipped products. Source: CEL   RF switches target test and measurement, Wi-Fi, sensors, appliances, and other radio equipped products. Source: CEL California Eastern Laboratories (CEL) has introduced a variety of Radio Frequency (RF) switches designed to be drop-in replacements for a wide range of existing RF products, as well as for new designs. Target markets include test and measurement systems, in addition to Wi-Fi, ZigBee and Bluetooth routers, sensors, appliances and other radio equipped products.
RF and microwave switches are used to route high frequency signals through transmission paths. They come in different configurations, providing the flexibility to create matrices and automated test systems for many different applications. Typical switch options include:  Single-pole-double-throw (SPDT or 1:2) switches that route signals from one input to two output paths. Multiport or single-pole-multiple-throw (SPMT) switches that allow a single input to multiple (three or more) output paths. Double-pole-double-throw (DPDT) switches can be used to switch between two inputs and two outputs
These low-cost RF Switches operate over frequency ranges through 6GHz and are drop-in compatible to various existing Renesas RF Switch products. (Renesas switches also offered through CEL).
Some of these new switches include: 
CG2179MT (SPDT) highly affordable, general purpose RF switch
CG2214M6 (SDPT) low cost general purpose RF switch with low insertion loss
CG2185X2 (SPDT) compact wideband RF switch for WLAN applications
CG2163X3 (SPDT) Wideband RF switch for WLAN providing high isolation features
CG2415M6 (SPDT) Wideband RF switch for WLAN that features medium power and high isolation
CG2430X1 (SP3T) Wideband RF switch for WLAN and Bluetooth
CG2176X3 (Absorptive SPDT) High Power, Wideband RF Switch for WLAN
