DESCRIPTION
The ultraminiature GRF100 and GRF103 relays
are designed to provide a practical surface-mount
solution with improved RF signal repeatability over the
frequency range. GRF100 and GRF103 relays feature
a unique ground shield that isolates and shields each
lead to ensure excellent contact-to-contact and poleto-
pole isolation. This ground shield provides a ground
interface that results in improved high-frequency
performance as well as parametric repeatability.
The GRF100 and GRF103 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 GRF100 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
• RoHS Compliant
