RF & MICROWAVE SERIES HIGH REPEATABILITY, NORMALLY OPEN, BYPASS RF RELAYS SERIES DESIGNATION RF320 RF323 RELAY TYPE RF320 Repeatable, RF, N.O. bypass relay RF323 Sensitive, repeatable, RF, N.O. bypass relay INTERNAL CONSTRUCTION PERFORMANCE FEATURES The ultraminiature RF320 and RF323 relays are designed with an internal bypass (through path), when the coil is energized, to provide low insertion loss UPPER STATIONARY CONTACT UNI-FRAME and VSWR through the bypass and simplicity of design for the user. Relays have improved RF insertion loss repeatability over the frequency range from MOVING CONTACT ARMATURE LOWER STATIONARY BYPASS CONTACT dc to 3 GHz. Highly suitable for use in attenuator, linear amplifier and other RF 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.
