DESCRIPTION
The ultraminiature SGRF300 and SGRF303 relays are designed to
provide a practical surface-mount solution with improved RF signal
repeatability over the frequency range. SGRF300 and SGRF303
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 SGRF300 and SGRF303 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 SGRF300 and SGRF303 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
The Series SGRF300D/SGRF303D and SGRF300DD/
SGRF303DD relays have internal discrete silicon diodes for coil
suppression and polarity reversal protection. This hybrid package
reduces required PC board floor space by reducing the number of
external components needed to drive the relay.
