DESCRIPTION

The ultraminiature GRF300 and GRF303 relays are

designed to provide a practical surface-mount solution

with improved RF signal repeatability over the frequency

range. GRF300 and GRF303 relays feature a unique

ground shield that isolates and shields each lead to

ensure excellent contact-to-contact and pole-to-pole

isolation. The GRF300/GRF303 version with the improved

ground connections can push the performance up into the

10Gbps data rates for digital signal integrity applications.

This ground shield provides a ground interface that

results in improved high-frequency performance as well

as parametric repeatability. The GRF300 and GRF303

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 GRF300 and GRF303 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
