High Quality QMA Female Bulkhead Mount Connector Crimp Solder Attachment for RG174 RG316 RG188 Cable
The QMA connector is a quick disconnect version of the SMA connector and shares the same internal construction, which allows the connector to have excellent performance up to 18 GHz. Because of the innovative coupling mechanism, a 360-degree butt joint is maintained resulting in low RF leakage. Since the RF line is identical to the SMA series, the QMA female bulkhead coaxial connector has an interface type of RG174 RG316 RG188 and a 50 Ohm impedance, it uses shield/contact crimp/solder as an attachment method, and provides a minimum frequency of DC and a maximum frequency of 18 GHz.
