RF312-5 Teledyne

SERIES HIGH REPEATABILITY RF312 8 GHz TO-5 RELAYS SIGNAL INTEGRITY TO 12Gbps DPDT SERIES RELAY TYPE DESIGNATION RF312 Repeatable, RF TO-5 relay PERFORMANCE FEATURES INTERNAL CONSTRUCTION The ultra miniature RF312 is designed to improve upon the RF300/RF303 relays high frequency performance. The RF312 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 RF312 features: High repeatability. Broader bandwidth. Metal enclosure for EMI shielding. Ground pin option to improve case grounding. High isolation between control and signal paths. Highly resistant to ESD. ENVIRONMENTAL AND CONSTRUCTION FEATURES PHYSICAL SPECIFICATIONS Storage 65C to +125C The following unique construction features and manufacturing Temperature techniques provide excellent resistance to environmental (Ambient) Operating 55C to +85C extremes and overall high reliability. Vibration 10 gs to 500 Hz (General Note 1) Uni-frame motor design provides high magnetic efficiency and mechanical rigidity. Shock 30 gs, (General Note 1) 6ms half sine Minimum mass components and welded construction Enclosure Hermetically sealed provide maximum resistance to shock and vibration. 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. 2008 Teledyne Relays (800) 284-7007 www.teledynerelays.com +44 (0) 1236 453124 www.teledyne-europe.com RF312 Page 1 RF312 012008 Q1SERIES RF312 TYPICAL RF CHARACTERISTICS (See RF Notes) Isolation Across Contacts (RF Note 3) Insertion Loss (RF Note 4) 0 0 -0.2 -10 -0.4 -0.6 -20 -0.8 -1 -30 Normally Closed -1.2 Normally Open -40 -1.4 Normally Closed -1.6 -50 Normally Open -1.8 -2 -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) VSWR (RF Note 4) Isolation Pole to Pole (RF Note 4) 0 2 1.9 -10 1.8 1.7 -20 1.6 Normally Closed 1.5 -30 Normally Open 1.4 De-Energized -40 1.3 Energized 1.2 -50 1.1 1 -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) Time Response (RF Note 4) 1.1 0.9 90% 0.7 37ps reference 0.5 62.3ps propagation delay time 0.3 51.1ps pulse rise time 10% 0.1 -0.1 -100 0 100 200 300 400 500 700 800 900 600 Time (ps) RF NOTES 1. Test conditions: a. Fixture: .031 copper clad, reinforced PTFE, RT/duroid 6002 with SMA connectors. (RT/duroid is a registered trademark of Rogers Corporation.) b. Relay header is in contact with, but not soldered to ground plane. c. Room ambient temperature. d. Terminals not tested were terminated with 50-ohm load. e. Contact signal level: 10 dBm. f. No. of test samples: 4. 2. Data presented herein represents typical characteristics and is not intended for use as specification limits. 3. Data is the average from readings taken on all open contacts. 4. Data is the average from readings taken on all closed contacts. 5. Test fixture effect de-embedded from frequency and time response data. 6. For enhanced RF performance solder the entire perimeter of header to the ground plane. Soldering only a partial amount of the header perimeter may result in reduced RF performance.
