The SGRF103-5 ultra miniature SGRF103 relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range. SGRF103 relays feature 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 highfrequency performance as well as parametric repeatability. The SGRF103 extend performance advantages over similar RF devices that simply offer formed leads for surface mounting.
