DESCRIPTION

The ultraminiature GRF700 and GRF703 relays are designed to provide a

practical surface-mount solution with improved RF signal repeatability over

the frequency range. GRF700 and GRF703 relays feature a unique ground

shield that isolates and shields each lead to ensure excellent contact-tocontact

and pole-to-pole isolation. This ground shield provides a ground

interface that results in improved high-frequency performance as well as

parametric repeatability. The GRF700 and GRF703 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 GRF700 and GRF703 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
