Surface Mount RF Switches Suit Broadband Applications


Fairview Microwave announced new high-reliability SPDT surface mount electromechanical RF switches that cover broadband frequencies from DC to 8GHz. The switches offer exceptional reliability and repeatable performance making them an ideal solution for applications in aerospace, defense, industrial, telecom, instrumentation, medical devices and many others.

With an operating voltage of +24 VDC, the switches utilize compact surface mount packages and are designed for high-rel performance rated for minimum two million life cycles. Incorporating either Failsafe or Latching Actuators, the devices offer exceptional performance over -40°C to +85°C including a maximum CW power rating of 400W, high isolation up to 50 dB and insertion loss as low as 0.1 dB.

The package assembly is fully RoHS compliant and the bottom side consists of a PWB mounting surface that’s gold plated and designed to resist the effects of oxidation for ease of soldering. Assembly instructions and downloadable PWB layout software are available from the website. The package design also has the ability to withstand exposure to MIL-STD-202 test conditions for sine and random vibration as well as mechanical shock.

“This innovative lineup of high power surface mount SPDT electromechanical switches is available from stock and offers designers the same level of exceptional performance and high reliability as with more traditional coaxial switches. The miniature package design features a gold plated mounting surface that resists oxidation and can easily be solder-mounted onto a PCB”, explains Brian McCutcheon, Vice President and General Manager at Fairview Microwave.
