GRF311-5 Teledyne

SURFACE MOUNT SERIES HIGH REPEATABILITY GRF311 8 GHz TO-5 RELAYS SIGNAL INTEGRITY TO 12 Gbps SPDT SERIES RELAY TYPE DESIGNATION GRF311 Repeatable, RF TO-5 relay INTERNAL CONSTRUCTION PERFORMANCE FEATURES The GRF311 offers monotonic insertion loss to 8 GHz. This improvement in RF insertion loss over the frequency range UNIFRAME UPPER STATIONARY makes these relays highly suitable for use in attenuator and other CONTACT RF circuits. The GRF311 features: MOVING CONTACT LOWER ARMATURE STATIONARY High repeatability. CONTACT Broader bandwidth. GROUND SHIELD Metal enclosure for EMI shielding. High isolation between control and signal paths. Highly resistant to ESD. CONSTRUCTION FEATURES The following unique construction features and manufacturing ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS techniques provide excellent resistance to environmental extremes and overall high reliability. Storage 65C to +125C Temperature (Ambient) Operating 55C to +85C Uni-frame motor design provides high magnetic efficiency Vibration and mechanical rigidity. 10 gs to 500 Hz (General Note 1) Minimum mass components and welded construction provide Shock 30 gs, (General Note 1) 6ms half sine maximum resistance to shock and vibration. Enclosure Hermetically sealed Advanced cleaning techniques provide maximum assurance Weight 0.09 oz. (2.55g) max. of internal cleanliness. Gold-plated precious metal alloy contacts ensure reliable switching. Hermetically sealed. Solderable leads. 2009 Teledyne Relays SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE GRF311 Page 1 (800) 284-7007 www.teledynerelays.com +44 (0) 1236 453124 www.teledyne-europe.comSERIES GRF311 TYPICAL RF CHARACTERISTICS (See RF Notes) GRF311 Isolation Across Contacts (RF Note 3) GRF311 Insertion Loss (RF Note 4) 0 0 -10 -0.5 -20 -1 -30 -1.5 Normally Closed -40 Normally Open Normally Closed -2 Normally Open -50 -2.5 -60 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 Frequency (MHz) Frequency (MHz) Pulse Response Characteristic GRF311 VSWR (RF Note 4) 1.1 2.8 1 2.6 0.9 Normally Closed 2.4 Normally Open 0.8 Reference 2.2 NC 0.7 NO 2 0.6 Input Pulse Rise Time: 37 ps 0.5 1.8 Propagation Delay Time: - NC : 56 ps - NO : 61 ps 0.4 1.6 0.3 Pulse Rise Time: 1.4 - NC : 48 ps - NO : 47 ps 0.2 1.2 0.1 1 0 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 -50 0 50 100 150 200 250 300 350 Frequency (MHz) Time (ps) RF NOTES 1.
