SMB series
SMB (super miniature B) series, which began its application in the 60s of last century, connects with snap-on mating structure, and works wonderfully at frequency of 0-4GHZ. Even smaller than SMA, and convenient plug/unplug feature, thus increase greatly interspaces availability, all of these make this series a wide application in sections as antenna, base, cable accessories, MIL/civil radio communication, VF system, etc.
Measure up to standards: GJB681, SJ50681
MIL-C-39012
IEC60169-10
CECC 22130
In demand of our customers, we have designed and developed the following SMB 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)
- Flange Straight end receptacle (flange mount, apply to transition from coaxial cable to micro-strip in microwave systems and components)
- Panel receptacle (flange mount, bulkhead mount, terminal type: inner conductor rear welding, 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)
