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.

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

effi 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.
