Series SGRF300/SGRF303 DPDT Non-Latching Electromechanical Relay Signal Integrity up to 18Gbps SURFACE MOUNT HIGH REPEATABILITY, BROADBAND TO-5 RELAYS DPDT SERIES RELAY TYPE SGRF300 Repeatable, RF relay SGRF303 Sensitive, repeatable, RF relay DESCRIPTION The following unique construction features and manufacturing The ultraminiature SGRF300 and SGRF303 relays are designed to techniques provide excellent robustness to environmental provide a practical surface-mount solution with improved RF signal extremes and overall high reliability: repeatability over the frequency range. SGRF300 and SGRF303 Uniframe motor design provides high magnetic efficiency relays feature a unique ground shield that isolates and shields and mechanical rigidity each lead to ensure excellent contact-to-contact and pole-to-pole Minimum mass components and welded construction provide isolation. This ground shield provides a ground interface that results maximum resistance to shock and vibration in improved highfrequency performance as well as parametric Advanced cleaning techniques provide maximum assurance of repeatability. The SGRF300 and SGRF303 extend performance internal cleanliness advantages over similar RF devices that simply offer formed leads Gold-plated precious metal alloy contacts ensure reliable switching for surface mounting.These relays are engineered for use in RF Hermetically sealed attenuator, RF switch matrices, ATE and other applications that require dependable high frequency signal fidelity and performance. The SGRF300 and SGRF303 feature: High repeatability Broader bandwidth Metal enclosure for EMI shielding High isolation between control and signal paths High resistance to ESD ENVIRONMENTAL AND INTERNAL CONSTRUCTION PHYSICAL SPECIFICATIONS Storage 65C to +125C Temperature (Ambient) Operating 55C to +85C Vibration 10 gs to 500 Hz (General Note I) Shock 30 gs, (General Note I) 6ms half sine Enclosure Hermetically sealed SGRF300 0.09 oz.
