6.25mm (.246”) Pitch Ganged RF Ganged RF System Connects High Bandwidth RF Signals In Blind-Mate Daughtercard Receptacles and Backplane Headers The Ganged RF system offers customers innovative packaging with selectively loaded housings for connecting up to 2.5GHz single-ended or analog RF signals. The blind-mate right-angle daughtercard receptacles and vertical backplane headers are available in three- and four-port sizes with selective loading of high-performance vertical signal pairs. The press-fit terminals allow simple termination to the PCB with optional application tooling available from Molex. Options for cabling in both sizes are also available in several standard lengths to connect with the right-angle daughtercard receptacles. Features and Benefits s 50 Ohm ±10% matched impedance contact system for low insertion loss and optimal signal integrity s 60 db min. isolation to minimize crosstalk s Press-fit termination and locator pegs promote easy and reliable board termination s Modular assembly of vertical signal pairs allow custom loading s High-temperature 94V-0 housings with generous chamfers and blind-mating lead-ins for reliable and consistent mating s Contacts with 0.76µm (30µ”) min. gold plating on mating surfaces for excellent reliability 74642, 74712 Right Angle Receptacle and Vertical Header SPECIFICATIONS Reference Information Packaging: Tray UL File No.: E107635 CSA File No.: 152514 (LR19980) Designed In: mm Electrical Voltage: 5.0 VAC Current: 1.0 A max.
