The ultraminiature SGRF100 and SGRF103 relays are
designed to provide a practical surface-mount solution with
improved RF signal repeatability over the frequency range.
SGRF100 and SGRF103 relays feature a unique ground
shield that isolates and shields each lead to ensure excellent
contact-to-contact and pole-to-pole isolation. This ground
shield provides a ground interface that results in improved highfrequency performance as well as parametric repeatability. The
SGRF100 and SGRF103 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 SGRF100 and SGRF103 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
