SURFACE MOUNT HIGH REPEATABILITY 8 GHz TO-5 RELAYS SIGNAL INTEGRITY TO 12 Gbps SPDT SERIES DESIGNATION RELAY TYPE GRF311 Repeatable, RF TO-5 relay INTERNAL CONSTRUCTION SERIES GRF311 PERFORMANCE FEATURES UNIFRAME UPPER STATIONARY CONTACT MOVING CONTACT LOWER STATIONARY CONTACT ARMATURE The GRF311 offers monotonic insertion loss to 8 GHz. This improvement in RF insertion loss over the frequency range makes these relays highly suitable for use in attenuator and other RF circuits. The GRF311 features: * High repeatability. * Broader bandwidth. * Metal enclosure for EMI shielding. GROUND SHIELD * High isolation between control and signal paths. * Highly resistant to ESD. CONSTRUCTION FEATURES ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) Storage -65C to +125C Operating -55C to +85C The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability. Vibration (General Note 1) 10 g's to 500 Hz * Uni-frame motor design provides high magnetic efficiency and mechanical rigidity. Shock (General Note 1) 30 g's, 6ms half sine * Minimum mass components and welded construction provide maximum resistance to shock and vibration. Enclosure Hermetically sealed Weight 0.09 oz. (2.55g) max. * Advanced cleaning techniques provide maximum assurance of internal cleanliness. * Gold-plated precious metal alloy contacts ensure reliable switching. * Hermetically sealed. * Solderable leads.
