Winchester Electronics is announcing the addition of the newly released QC-SMA™ series of RF connectors to its standard product line. The QC-SMA series incorporates a push/pull style of mating that does not require torque wrenches or any other tool for mating or unmating. This revolutionary new series is also backwards compatible to existing jack connectors in the field. Typical applications for this connector could be in PCB test boards, microwave subsystems, base stations, test equipment, mobile radios and anywhere a quick connection is required.
These new connectors offer several benefits:
• The push/pull connection system allows quicker mating
• When mated, the connectors can be rotated 360°
• Their electrical performance is comparable to standard SMAs, up to 6 GHz
• Their compact design utilizes the SMA standard spacing down to 0.5 inch center to center
• Designs are available for both flexible and semi-rigid types of cable
Figure 1 shows the sequence of the mating operations. First, in the open, unmated state, the shroud is pulled back. The QC connector is then pushed into its mate while holding onto the shroud. The mating is completed by pushing the shroud forward. Table 1 shows the electrical characteristics of the QC-SMA connectors.
The body and outer contact are made of a copper alloy while the body components and male contacts are made of brass per ASTM B16. The insulators use PTFE (Teflon) per ASTM D1710. The crimp ferrules are made of copper alloy. The center contacts are gold plated (ASTM B4888) over a nickel plate (QQ-N-290). The other metal parts are gold, nickel or tri-metal plated to meet the corrosion requirements of MIL-PRF-39012. The mating or unmating force is 10 lbs maximum while the fully mated connector retention force is 30 lbs minimum. The durability of the connector exceeds 500 cycles. The temperature rating of the QC-SMA connector is – 65° to +165°C.
