Radiall has expanded its RAMSES R570 coaxial relay series with a new 50 GHz SPDT (single pole double throw) switch featuring three 2,4 mm connectors. Designed for the instrumentation market, the switch is suitable for precision requirements in test and measurement applications where high frequency and excellent RF performance are necessary.
The Radiall Modular System for Electromechanical Switches (RAMSES) is a patented technology that enables microwave coaxial switches to be produced with a typical operating life of ten million cycles without a decrease in contact resistance reliability over time. In addition, the unique internal construction makes the switches modular, which reduces the cost and lead time.
All RAMSES configurations are applicable to the 50 GHz SPDT switch and are now available with failsafe or latching versions, 12 or 28 V and three 2,4 mm connectors. Other options include TTL driver, self cutoff and indicators. The switch is optimised for RF performance with an insertion loss 0,7 dB, VSWR of 1,55 and an isolation of 80 dB, all typical at 50 GHz. In addition, it has a life cycle of 2 million and an actuator terminal with solder pins.
