DESCRIPTION
The ultra miniature RF312 is designed to improve upon
the RF300/RF303 relay’s high frequency performance. The
RF312/RF332 o ers monotonic insertion loss to 8 GHz.
This improvement in RF insertion loss over the frequency
range, makes these relays highly suitable for use in
attenuator and other RF circuits. The sensitive RF332 relay
has a high resistance coil, thus requiring extremely low
operating power (200 mW typical). The advantages of
reduced heat dissipation and power supply demands are a
plus. The RF312/RF332 features:
• High repeatability.
• Broader bandwidth.
• Metal enclosure for EMI shielding.
• Ground pin option to improve case grounding.
• High isolation between control and signal paths.
• Highly resistant to ESD.
CONSTRUCTION FEATURES
The following unique construction features and
manufacturing techniques provide excellent resistance to
environmental extremes and overall high reliability.
• Uni-frame motor design provides high magnetic
e ciency and mechanical rigidity.
• Minimum mass components and welded construction
provide maximum resistance to shock and vibration.
• Advanced cleaning techniques provide maximum
assurance of internal cleanliness.
• Gold-plated precious metal alloy contacts ensure
reliable switching.
• Hermetically sealed.
• Solder-Dipped Leads, (RoHS compliant solder option
available)
