The Centigrid® RF100 and GRF100 repeatable RF relays, along with the Centigrid® RF103 and GRF103 sensitive repeatable RF relays are ultra-miniature, hermetically sealed with DPDT contact configurations designed to provide improved RF signal repeatability over the frequency range.
The through hole mount RF103 (stock number 758-2509) and the surface mount GRF103 (stock number 758-2470) are sensitive coil versions of the through hole mount RF100 (stock numbers 399-9414 and 399-9420), they have twice the coil resistance of the standard versions so require half the power to operate.
Both the sensitive and standard types have a 2.54mm Centigrid® pitch. The RF100 (399-9414 and 399-9420) have a 7.37mm profile height, the RF103 (758-2509) has a 10.03mm profile, the GRF103 (758-2470) has a 11.05mm profile height.
The surface mount GRF100 and GRF103 Centigrid® 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 high frequency performance as well as parametric repeatability.
These Centigrid® relays are designed for use in RF attenuator switching in Test & Measurement applications, bypass and combiner switching functions in GSM applications, wireless LAN and many other applications that require dependable high performance in which high speed signals must be transferred.
