Surface Mounting Type, RF Relays

GRF172 Series surface mount RF relays are designed to provide excellent RF signal repeatability.
The GRF172 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.
