SBMA series
SBMA is super miniature-size BMA, with basically all the same structures but the tinier size which provides high density layout within modules, and connect easily. It applies widely in MIL/civil microwave communication.
Measure up to standards:GJB681, SJ50681
MIL-C-39012
In demand of our customers, we have designed and developed the following SBMA 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)
- On-spot replaceable receptacle (flange mount, panel-thread mount, in circumstances replacement is needed)
- Panel receptacle (flange mount, panel-thread mount, panel-crimp mount, suit for transition from coaxial cable to micro-strip line in microwave systems and components)
