SSMA series
To meet the need of SMA series’ application in fields of smaller space and higher frequency, SSMA series was invented consequently. SSMA series has the same outlook as SMA, but tinier dimensions (thread mounting: 10-36 UNS), it works at frequency of DC-38GHZ, plus its unique features of reliable connection, condition-durability and other electrical performance, it has been widely used in sections as: radar, MIL/space, apparatus and instruments, equipment test and mobile communication, etc.
Measure up to standards:GJB681, SJ50681, SJ50976
MIL-C-39012
IEC60169-18
CECC 22140
In demand of our customers, we have designed and developed the following SSMA 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, applied to transition from coaxial cable to micro-strip in microwave systems and components)
- Straight end receptacle (flange mount, apply to the transition from coaxial cable to micro-strip cable, strip-shape cable printed substrate and wave guide)
- 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 (4-pin welding mount, apply to the transition from coaxial cable to printed circuit board)
