GRF300-12产品概述
The ultraminiature GRF300 and GRF303 relays are designed to provide a
practical surface-mount solution with improved RF signal repeatability over
the frequency range. GRF300 and GRF303 relays feature a unique ground
shield that isolates and shields each lead to ensure excellent contact-tocontact
and pole-to-pole isolation. The GRF300/GRF303 version with
the improved ground connections can push the performance up into the
10Gbps data rates for digital signal integrity applications. This ground
shield provides a ground interface that results in improved high-frequency
performance as well as parametric repeatability. The GRF300 and GRF303
extend performance advantages over similar RF devices that simply offer
formed leads for surface mounting. These relays are engineered for use in
RF attenuator, RF switch matrices, ATE and other applications that require
dependable high frequency signal fidelity and performance.
The GRF300 and GRF303 feature:
High repeatability
Broader bandwidth
Metal enclosure for EMI shielding
High isolation between control and signal paths
High resistance to ESD
The following unique construction features and manufacturing techniques
provide excellent robustness to environmental extremes and overall high
reliability:
Uniframe 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
