Hengyu Consolidates RF Coaxial Portfolio Under GJB681A-2002
Executive Summary
Guangzhou Hengyu Electronic Technology Co., Ltd. now offers its principal RF coaxial families against a single qualification reference — GJB681A-2002, the national military standard equivalent to MIL-C-39012 — giving designers one document set across six interface types.
Guangzhou Hengyu Electronic Technology Co., Ltd. has completed the alignment of its RF coaxial connector range under GJB681A-2002 (MIL-C-39012). The change is a documentation and testing consolidation rather than a new product line: families that were previously specified against separate references are now qualified and published against one standard.
One Reference Across Six Interfaces
The portfolio now spans SMA, SMB, SSMB, MCX, MMCX, BNC and N, with the high-frequency BMA range carried against IEC 61169-33. Each family retains its own electrical envelope — SMA to 18 GHz on semi-rigid cable, N to 11 GHz, BNC and SMB to 4 GHz, SSMB to 3 GHz, MCX and MMCX to 6 GHz — while sharing a common qualification basis, common contact plating and a common inspection regime.
What This Changes for Designers
- One qualification document covers the RF interface across the range, simplifying design reviews and second-source approval.
- Consistent contact materials — gold-plated phosphor bronze pins and beryllium copper sockets throughout, on PTFE dielectric.
- Comparable published data — frequency range, VSWR, dielectric withstanding voltage, insulation resistance and cycle life are stated on the same basis for every family, so cross-family selection no longer means reconciling different datasheet conventions.
- A single point for custom variants — non-standard cable interfaces, flange patterns and impedance-matched assemblies can be quoted against the same reference.
Range Summary
- SMA — DC to 12.4 GHz flexible / 18 GHz semi-rigid, VSWR ≤ 1.15 + 0.02f, 1000 V.
- SMB — DC to 4 GHz, VSWR ≤ 1.3, 750 V.
- SSMB — DC to 3 GHz, 500 V.
- MCX — DC to 6 GHz, VSWR ≤ 1.3, 750 V.
- MMCX — DC to 6 GHz, VSWR ≤ 1.3, 500 V.
- BNC — DC to 4 GHz, VSWR ≤ 1.3, 1500 V, bayonet coupling.
- N — DC to 11 GHz, VSWR ≤ 1.3, 1500 V, threaded coupling.
Manufacturing Background
The RF range is produced alongside the company's circular, rectangular and PCB connector lines at its Guangzhou facility, covering military-specification circular connectors to GJB599 (MIL-DTL-38999), Micro-D connectors to GJB2446 (MIL-C-83513), D-subminiature connectors to GJB142A (MIL-C-24308) and high-density rectangular connectors. Custom cable assemblies and non-standard shell configurations are quoted against the same qualification references.
Availability
Datasheets for each family, including interface dimensions and panel cutouts, are available on request. Samples of standard catalogue parts are available for evaluation, and custom variants are quoted with a defined qualification path against GJB681A-2002.
