BMA Series

BMA Series
Description
BMA connectors are 50-ohm with slide-on mating &
Specification
BMA
BMA connectors feature a push-on interface and a threadless outer ground connection. They can
withstand both radial and axial misalignment. BMA connectors are miniature BMA connector.
BMA connectors also includes a unique First-Make-Last-Break (FMLB) ground contact, which allows
modular components to be plugged and unplugged or "hot swapped" in and out of a live system.
non-locking interface that accomplish feature of
blindmate.
The feature of blindmate has an external spring to

provide mechanical movement for extensive
mechanical misalignment of ± .020 radial and .060

microwave applications such as wireless infrastructure,
satellite equipment and test and measurement.
BMA also offer good electrical performance up to
18GHz and approximately the same size as SMA
