CONSTRUCTION FEATURES
DESCRIPTION
The ultra miniature GRF312 is designed to improve
upon the GRF300/GRF303 relay’s high frequency
performance. The GRF312/GRF332 offers 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 GRF332 relay has a high
resistance coil, thus requiring extremely low operating
power (200 mW typical).
• High repeatability.
• Broader bandwidth.
• Metal enclosure for EMI shielding.
• High isolation between control and signal paths.
• Highly resistant to ESD.
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
efficiency 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.
