Series GRF300/GRF303 DPDT Non-Latching Electromechanical Relay Signal Integrity up to 18Gbps SURFACE MOUNT HIGH REPEATABILITY, BROADBAND TO-5 RELAYS DPDT SERIES RELAY TYPE GRF300 Repeatable, RF relay GRF300D Repeatable, RF relay with internal diode for coil transient suppression Repeatable, RF relay with internal diodes for coil transient suppression and polarity reversal GRF300DD protection GRF303 Sensitive, repeatable, RF relay GRF303D Sensitive, repeatable, RF relay with internal diode for coil transient suppression Sensitive, repeatable, RF relay with internal diodes for coil transient suppression and polarity GRF303DD reversal protection DESCRIPTION High isolation between control and signal paths The ultraminiature GRF300 and GRF303 relays are designed to provide a High resistance to ESD practical surface-mount solution with improved RF signal repeatability over the frequency range. GRF300 and GRF303 relays feature a unique ground The following unique construction features and manufacturing techniques shield that isolates and shields each lead to ensure excellent contact-to- provide excellent robustness to environmental extremes and overall high contact and pole-to-pole isolation. The GRF300/GRF303 version with reliability: the improved ground connections can push the performance up into the Uniframe motor design provides high magnetic efficiency and 10Gbps data rates for digital signal integrity applications. This ground mechanical rigidity shield provides a ground interface that results in improved high-frequency Minimum mass components and welded construction provide maximum performance as well as parametric repeatability. The GRF300 and GRF303 resistance to shock and vibration extend performance advantages over similar RF devices that simply offer Advanced cleaning techniques provide maximum assurance of internal formed leads for surface mounting. These relays are engineered for use in cleanliness RF attenuator, RF switch matrices, ATE and other applications that require Gold-plated precious metal alloy contacts ensure reliable switching dependable high frequency signal fidelity and performance. Hermetically sealed The GRF300 and GRF303 feature: The Series GRF300D/GRF303D and GRF300DD/GRF303DD relays have internal discrete silicon diodes for coil suppression and polarity reversal High repeatability protection.This hybrid package reduces required PC board floor space Broader bandwidth by reducing the number of external components needed to drive the relay.
