QMA jack to SMA plug adaptor

TE Connectivity - QMA

Providing the same high quality and performance found in Tyco’s SMA products, the QMA series offers the added benefit of snap-on connection. By integrating a snap on feature to the design, denser packaging can be achieved and the overall applied cost is dramatically reduced. The QMA connector series is completely intermateable with competitive QMA offerings, however, it is not intermateable with standard SMA interfaces.

Positive snap-on interface facilitates assembly
Excellent RF performance to 6 GHz
Ideal for communications and industrial applications
