Keywords:Broadband? RF switches?

Fairview Microwave rolled out electromechanical relay switches that cover ultra-broadband and millimeter-wave frequencies up to 40GHz. The RF switches perform up to two to 10 million life cycles, making them suitable for applications in defence and commercial aviation, radar, wireless communications, satellite communications, test and measurement.

The coaxial relay switches are available in multiple varieties from SPDT (Single Pole Double Throw) to SP12T (Single Pole 12 Throw) and are designed with either SMA, Type-N, or 2.92mm depending on the frequency range.

Frequencies for these RF switches range from DC to 40GHz depending on the model, power ratings range from 5W to 700W, operating voltage ranges from 12V to 30V and have high isolation up to 85 dB and low insertion loss of 0.15dB at 1GHz.

Fairview's new relay switches have a patented design of the actuator and the transmission link has been optimised for magnetic efficiency and mechanical rigidity which is what guarantees operation up to 10 million life cycles. The MIL-STD-202 qualified construction of each switch is designed to withstand exposure to sine and random vibration and mechanical shock. Offered in this release are 42 in-stock designs which include 38 connectorised models and four surface-mount devices which boast a small footprint and lower cost than traditional connectorised packages.

"Our latest offering of high reliability relay switches provide our customers a new comprehensive selection of in-stock RF switches, not widely available off-the-shelf," explained Brian McCutcheon, VP and general manager at Fairview Microwave. "With guaranteed performance up to 10 million life cycles on many models, these switches provide an excellent value to customers requiring long-term and accurate performance."

Fairview's electromechanical relay switches are in-stock and available today.
