GRF312
GRF312 is Surface-Mount RF relay manufactured by Teledyne Technologies.
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 m W 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 efficiency and mechanical rigidity.
- Minimum mass ponents 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.
