GRF300 Datasheet | Teledyne Technologies

DESCRIPTION The ultraminiature GRF300 and GRF303 relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range. GRF300 and GRF303 relays feature a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole-to-pole isolation. The GRF300/GRF303 version with the improved ground connections can push the performance up into the 10Gbps data rates for digital signal integrity applications. This ground shield provides a ground interface that results in improved high-frequency performance as well as parametric repeatability. The GRF300 and GRF303 extend performance advantages over similar RF devices that simply offer formed leads for surface mounting. These relays are engineered for use in RF attenuator, RF switch matrices, ATE and other applications that require dependable high frequency signal fidelity and performance. The GRF300 and GRF303 feature : - High repeatability - Broader bandwidth - Metal enclosure for EMI shielding - High isolation between control and signal paths - High resistance to ESD The following unique construction features and manufacturing techniques provide excellent robustness to environmental extremes and overall high reliability: - Uniframe motor design provides high magnetic efficiency and mechanical rigidity - Minimum mass ponents and welded construction provide maximum resistance to shock and vibration - Advanced cleaning techniques provide maximum assurance of internal cleanliness - Gold-plated precious metal alloy contacts ensure reliable switching - Hermetically sealed ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature Storage - 65°C to +125°C (Ambient) Operating - 55°C to +85°C Vibration (Note 1) 10 g’s to 500 Hz Shock (Note 1) 30 g’s, 6ms half sine Enclosure Hermetically sealed Weight GRF300 GRF303 0.09 oz.
