The ultraminiature GRF312 relay is designed to improve upon the GRF300/GRF303 relay's high frequency performance. The GRF312 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 GRF312 features: · High repeatability. · Broader bandwidth. · Metal enclosure for EMI shielding.

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. RF ground shield is soldered to PCB RF 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: 2. Data presented herein represents typical characteristics and is not intended for use as specification limits. Data is per pole, except fpr pole-to-pole data. Data is the average from readings taken on all open contacts. Data is the average from readings taken between poles with coil energized and de-energized. Data is the average from readings taken on all closed contacts. Test fixture effect de-embedded from frequency and time response data.
