RF RELAYS<br />
Series RF312/RF332 Electromechanical <strong>Relays</strong><br />
The RF312/RF332 is designed to improve upon the RF300/RF303 relay’s high frequency performance. The<br />
RF312/RF332 offers monotonic insertion loss over to 8GHz. This improvement in RF insertion loss over the<br />
frequency range, makes these relays highly suitable for use in attenuator and other RF circuits. The<br />
RF312/RF332 Series is offered with a standard or sensitive coil. The GRF312/GRF332 is designed to<br />
improve upon the GRF300/GRF303 relay’s high frequency performance. The GRF312/GRF332 TO-5 relay<br />
features a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact<br />
and pole-to-pole isolation. This ground shield provides a ground interface that results in improved highfrequency<br />
performance as well as parametric repeatability. The SGRF312/SGRF332 feature a unique ground<br />
shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation.<br />
