The GRF103-5 ultra miniature relays is designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range. This relay features 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 high-frequency performance as well as parametric repeatability. This extend performance advantages over similar RF devices that simply offer formed leads for surface mounting. This relay is engineered for use in RF attenuator, RF switch matrices, ATE and other applications that require dependable high frequency signal fidelity and performance.
