High performance, low cost RF switches for communications

January 19, 2017 // By Jean-Pierre Joosting
Compact, highly reliable RF switches that are ideal for optimizing transceiver performance for a wide range of IoT, industrial, smart home, medical, automotive and RF test applications, a variety of low-cost RF switches from CEL have been designed as easy drop in replacements for a wide range of existing RF products as well as for new designs.

Target markets include test and measurement systems as well as 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 (SPnT) 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 6-GHz and are drop-in compatible to various existing Renesas RF switch products. (Renesas switches also offered through CEL).

“Our new RF switch portfolio provides customers with a comprehensive selection of high performance devices that are extremely reliable and cost competitive,” says Marc Sheade, Vice President and General Manager, Components Business.
