SURFACE MOUNT, HIGH REPEATABILITY, SIGNAL INTEGRITY TO 10Gpbs BROADBAND TO-5 RELAYS

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.

Features:

• High repeatability
