- Fairview Microwave has introduced 28 new waveguide electromechanical relay switches from 5.85 GHz to 40 GHz that cover C, X, Ku, K and Ka Frequency Bands.
- They are intended for applications that include VSAT, SATCOM, radar, microwave radio, electronic warfare, electronic countermeasures, research and development, space systems and test instrumentation.
Fairview’s new waveguide electromechanical relay switches are configured for single-pole double-throw (SPDT) operation with latching actuators, self-cut-off, TTL logic, and position indicators with manual override. A shorting plate can be removed for optional double-pole double-throw (DPDT) operation.
All switches incorporate a patented motor drive with arc suppression and include an environmentally sealed, quick-connect DC control connector and mate.
These switches boast a compact package design with integrated waveguide ports with grooved flanges and O-rings for pressurized operation (up to 30 PSIG). They are available in a selection of waveguide sizes that include WR137, WR112, WR90, WR75, WR62, WR42 and WR28.
These waveguide electromechanical relay switches feature high isolation levels up to 105 dB, and low insertion loss down to 0.01 dB.
Models are specified with operating voltages of either +12 or +28 Vdc and feature power handling capability of up to 12 kW CW and 320 kW peak (unpressurized, 10% duty cycle) in a break before make condition.
These rugged designs operate in temperatures ranging from -40°C to +85°C, are rated for 250K lifecycles minimum, and packages are fully weatherized for exposure up to 100% humidity.
