Allen, TX. Fairview Microwave Inc., a supplier of on-demand microwave and RF components, has announced a new line of high-reliability SPDT surface-mount electromechanical RF switches that cover broadband frequencies from DC to 8 GHz. These new RF switches offer the reliability and repeatable performance to make them suitable for aerospace, defense, industrial, telecom, instrumentation, medical-device, and other applications.
The new switches are designed for high-rel performance rated for 2 million life cycles minimum. They incorporate either failsafe or latching actuators. They operate from -40°C to +85°C and include a maximum CW power rating of 400 W, high isolation up to 50 dB, and insertion loss as low as 0.1 dB. Operating voltage is +24 VDC.
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 vendor’s website. Another key feature with the package design is 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,” explained Brian McCutcheon, vice president and general manager at Fairview Microwave. “The miniature package design features a gold plated mounting surface that resists oxidation and can easily be solder-mounted onto a PCB.”
