The SGRF303-5 ultra miniature SGRF303 Series relays are designed to provide a practical surface-mount solution with improved RF signal repeatability over the frequency range. SGRF303 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 SGRF303 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.
