DESCRIPTION

INTERNAL CONSTRUCTION

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.
