Single pole double throw switch added to Radiall’s RAMSES R570 coaxial relay products

Posted by John McHale
CHANDLER, Ariz., 12 March 2011. The RAMSES R570 coaxial relay series for test and measurement applications from Radiall has a 50 GHz Single Pole Double Throw (SPDT) switch.
The new switch uses three 2.4 millimeter connectors. The device is targeted for high frequency test and measurement applications that require strong radio frequency (RF) performance.
The Radiall Modular System for Electromechanical Switches (RAMSES) is a 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. Most competitive products can only achieve one million cycles. 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 volts and three 2.4 millimeter connectors. Other additional options include: TTL driver, self cutoff, and indicators.
The RAMSES SPDT Switch is optimized for RF performance with an insertion loss 0.7 dB, VSWR 1.55, and an isolation 80 dB all typical at 50 GHz. In addition, it also has a life cycle of 2 million and an actuator terminal with solder pins.
