BMA series(RF Coaxial Connector Products)
BMA is blind-mated connector, with a rational floated clearance range which ensure save and reliable blind-mated between module to module, module to mother-board, and works at frequency as high up to 22GHZ. Furthermore, it is tiny size, connected conveniently and possesses other electrical performance, so applied widely in MIL/civil microwave communication.
Measure up to standards: GJB681, SJ50681
MIL-C-39012
IEC61169-33
In demand of our customers, we have designed and developed the following BMA series connectors:
- Semi-rigid, semi-flexible coaxial cable plug and receptacle (compatible for .085 and . 141 semi-rigid, semi-flexible coaxial cable)
- Flexible cable plug and receptacle ( for all kinds of SYV, SFF, RG flexible cable)
- micro-strip receptacle ( flange mount, panel-thread mount, panel-crimp mount, applied to transition from coaxial cable to micro-strip in microwave systems and components)
- On-spot replaceable micro-strip receptacle (flange mount, panel-thread mount, in circumstances replacement is needed)
- Straight end receptacle (flange mount, apply to the transition from coaxial cable to micro-strip cable, strip-shape cable and printed substrate)
- Printed circuit board receptacle (welding mount, apply to the transition from coaxial cable to printed circuit board)
