circuits. The RF 320 and RF323 feature:
• N.O. bypass configuration.
• Repeatable insertion loss.
• Broad bandwidth.
• Metal enclosure for EMI shielding.
• Ground pin option to improve case RF grounding.
• High isolation between control and signal paths.
• High resistance to ESD.

b. Relay header is not soldered to ground plane or connected to ground via ground pin.
c. Test performed at room ambient temperature.
d. Terminals not tested were terminated with 50-ohm load.
e. Contact signal level: 0 dBm.
Data presented herein represents typical characteristics and is not intended for use as specification limits.
Data is per pole.
Measurement points are from pins 2 & 4 to pins 6 & 8.
Data is the average of both N.C. contacts to the bypass path.
Relays operate at frequencies above 3 GHz with reduced RF performance characteristics.
