DESCRIPTION
INTERNAL CONSTRUCTION
The ultraminiature SGRF100 and SGRF103 relays are
designed to provide a practical surface-mount solution with
improved RF signal repeatability over the frequency range.
UNIFRAME
UPPER
SGRF100 and SGRF103 relays feature a unique ground
STATIONARY
CONTACT shield that isolates and shields each lead to ensure excellent
contact-to-contact and pole-to-pole isolation. This ground
LOWER
ARMATURE
shield provides a ground interface that results in improved high-
STATIONARY
CONTACT
frequency 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
SHOWN WITHOUT GROUND SHIELD
switch matrices, ATE and other applications that require
dependable high frequency signal fidelity and performance.
