RF NOTES
1. Test conditions: a. Fixture: .031" copper clad, reinforced PTFE, RT/duroid(R) 6002 with SMA connectors. (RT/duroid(R) is a registered trademark of Rogers Corporation.) b. Room ambient temperature. c. Terminals not tested were terminated with 50-ohm load. d. Contact signal level: -10 dBm. e. No. of test samples: 4. Data presented herein represents typical characteristics and is not intended for use as specification limits. Data is per pole, except for pole-to-pole data. Data is the average from readings taken on all open contacts. Data is the average from readings taken on 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.

RF NOTES
1. One million cycle repeatability data is based upon 396 observations with an average repeatability 0.033 dB and a range of 0.093 dB. 2. Repeatability of attenuation values were obtained from tests conducted in a 20 dB attenuator network with a 0 dBm input signal. 3. Relay operates at frequencies higher than 3 GHz with reduced RF performance characteristics. 4. Curves were developed from tests performed on a 0.031" copper clad, reinforced PTFE circuit board at 20C (ref). The unutilized contacts were terminated in 50 ohms; characteristic impedance of measuring equipment is 50 ohms. The relays were mounted flush to the circuit board ground plane without the relay header soldered to the ground plane.
