High-frequency DPDT relays

24 July 2013 Switches, Relays & Keypads

The miniature (9,52 x 8 x 8,51 mm) GRF300 and GRF303 relays from Teledyne Relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range.

The double-pole double-throw relays feature a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation. The version with the improved ground connections can push the performance up into the 10 Gbps data rates for digital signal integrity applications.

These relays are engineered for use in RF attenuators, RF switch matrices, ATE and other applications that require dependable high-frequency signal fidelity and performance. They feature a metal enclosure for EMI shielding, high isolation between control and signal paths, and high resistance to ESD.

The GRF300 and GRF303 series have a stub pin surface-mount option and are also available with one or two diodes. The GRF300D/GRF303D model has an internal diode for coil transient suppression and the GRF300DD/GRF303DD model has internal diodes for coil transient suppression and polarity reversal protection.
