Teledyne Relays Announces New GRF424 4PST Relay Series
New Magnetic Latching GRF424/GRF424D Relay with Signal Integrity Performance Measured up to 10Gbps
Hawthorne, CA, April 2013: Teledyne Relays introduces the GRF424/GRF424D family!
The GRF424/GRF424D series relay is an ultraminiature, hermetically sealed, magnetic-latching relay featuring low intercontact capacitance for exceptional RF performance from DC-8 GHz. The GRF424/GRF424D feature a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation. This ground shield provides a ground interface which results in improved high-frequency performance as well as parametric repeatability. This RF relay consists of 4 SPST relays in one package compared to 4 individual SPST relays. Its low profile and small size make it ideal for applications where extreme packaging density and/or close PC board spacing are required. Due to its minimal mass, many relays may be used to configure replacements for bulkier switching solutions at a substantial savings in weight. These design features make these unique relays the perfect choice for use in RF attenuators, RF switching matrices and other RF applications requiring low insertion loss and low VSWR. The GRF424/GRF424D performs well up to 8GHz while competitor parts only perform well to 1GHz. The basic operating mechanism is similar to the TO-5 422 series relay.
The GRF424/GRF424D feature: high repeatability, broader bandwidth, metal enclosure for EMI shielding, high isolation between control and signal paths and high resistance to ESD. The GRF424 relay is ideally suited for applications where power dissipation must be minimized. These relays can be operated with a short duration pulse. After the contacts have transferred, no external holding power is required. The magnetic latching feature of the GRF424 series provides a nonvolatile "memory" capability since the relays will not reset upon removal of coil power. The GRF424/GRF424D series utilizes discrete diodes for coil transient suppression.
The GRF424/GRF424D Series measures .370 x .365 x .335 inches (9.4, 9.27, 8.51 cm) excluding leads and weighs .1 ounce (2.9g).
