RF RELAYS<br />

Series RF424/GRF424/SGRF424 Electromechanical <strong>Relays</strong><br />

The Series RF424/GRF424/SGRF424 relay is an ultraminiature, hermetically sealed, magnetic-latching relay<br />

featuring low intercontact capacitance for exceptional RF performance from DC-8 GHz. Its low profi le and<br />

small size make it ideal for applications where extreme packaging density and/or close PC board spacing are<br />

required. The RF424 Series features a unique ground shield that isolates and shields each lead to ensure<br />

excellent contact-to-contact and pole-to-pole isolation. This ground shield provides a ground interface that<br />

results in improved high-frequency performance as well as parametric repeatability.<br />

• Excellent Signal integrity up to 12Gbps<br />

• Hermetically Sealed<br />

• High Resistance to ESD<br />

• Metal Enclosure for EMI shielding<br />

• High Repeatability<br />

• Broader bandwidth<br />

• Through-hole or surface-mount<br />

confi gurations<br />
