DESCRIPTION
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-
to-contact 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
• Minimum mass components and welded construction
• Advanced cleaning techniques provide maximum
• Gold-plated precious metal alloy contacts ensure reliable
• Hermetically sealed
and mechanical rigidity
provide maximum resistance to shock and vibration
assurance of internal cleanliness
