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 20°C (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.
