Pasternack, Inc., a leading supplier of RF, microwave, and millimeter wave products, has launched 28 new waveguide electromechanical relay switches that deliver full waveguide performance across the C, X, Ku, K, and Ka bands. These advanced switches are ideal for use in critical applications such as electronic warfare, radar systems, satellite communications, microwave radio, VSAT, R&D, space systems, and test instrumentation.
The single-pole double-throw (SPDT) relay features a self-cutting latch brake, TTL logic control, and a position indicator for manual override. The double-pole double-throw (DPDT) version offers optional short-circuit removal. All models are equipped with a patented motor drive system that includes arc suppression, a sealed quick-connect DC control connector, and an adapter. The compact design integrates a waveguide port with slotted flanges and O-rings for pressurization up to 30 PSIG. Available sizes include WR137, WR112, WR90, WR75, WR62, WR42, and WR28, offering flexibility for various applications.
These switches are designed for high-performance environments. They feature an insertion loss as low as 0.01 dB, isolation up to 105 dB, and a switching speed between 54 to 76 milliseconds. They support both +12V and +28V DC voltage ratings and can handle up to 12 kW continuous power and 320 kW peak power (unpressurized, 10% duty cycle). With an operating temperature range from -40°C to +85°C and resistance to 100% humidity, these switches are built to last. Their durability ensures a minimum life of 250,000 insertions.
According to Mr. Tim Galla, Pasternack’s product manager, "Designers have been impressed by the versatility of our new wideband waveguide electromechanical switches, which offer self-cutting latch brakes, TTL logic, and indicators suitable for energy routing and radar applications. Unlike traditional switches that often require several months of lead time, all 28 of these new Pasternack products are available for immediate delivery."
All 28 waveguide electromechanical relay switches are currently in stock and can be shipped without minimum order requirements. For more information, visit [https://information](https://information).
