TYPICAL RF CHARACTERISTICS (See RF Notes)
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.
2. Data presented herein represents typical characteristics and is not intended for use as specification limits.
3. Data is per pole, except for pole-to-pole data.
4. Data is the average from readings taken on all open contacts.
5. Data is the average from readings taken on poles with coil energized and de-energized.
6. Data is the average from readings taken on all closed contacts.
7. Test fixture effect de-embedded from frequency and time response data.
