RF Relays Deliver High Signal Repeatability

A family of Centigrid relays is said to offer enhanced insertion loss repeatability. The RF100 and RF103 (basic and sensitive-coil versions) provide RF signal repeatability to ±0.1 dB or better, characterized from dc to 4 GHz. Enhanced RF performance has been designed in by balancing the aggregate insertion loss elements of the relays' design, it's claimed. The devices are suitable for use in attenuator and other RF circuits. They also feature a metal enclosure for EMI shielding, a ground-pin option to improve case grounding, high isolation between control and signal RF paths, and higher resistance to ESD. Available coil voltages are 5 vdc and 12 vdc.
