RF connectivity within devices
Devices are often designed based on multiple boards and modules. This brings several advantages, such as modularisation and higher flexibility in design questions.
Since most devices have wireless or cellular connectivity, or require transmission of high data rates between boards, a highly flexible and low-cost solution for transmitting RF signals between boards and/or building blocks is required.
Eliminating cabling for reducing costs is common in today’s industry; however, this may increase mechanical stress significantly, since in most cases, a solution for a mechanical overdetermined system needs to be provided. To overcome this, whilst continuing to maintain excellent electrical properties, board-to-board connectors need to be employed.
HUBER+SUHNER offers different board-to-board solutions, including MMBX, MFBX and MBX, allowing board-to-board, board-to-panel and board-to-board-through-panel connectivity. This technology brings features such as blind-mateability and large axial and radial working ranges.
In some cases, whether due to larger distances or other reasons, the solution might be required to use cables between modules. HUBER+SUHNER offers a wide range of connectors and cables for these applications. Board-to-board connectors can also be used in conjunction with cable connectors or other small size connectors might also be feasible. For very high performance and low space requirements, there are also cable connectors with bend-to-the-edge technology available.
RF cables (performance line)
The PTFE/FEP cables of our RG/K series are designed for applications up to 200 °C and are characterised by low losses, especially at high frequencies. The Enviroflex cables do not contain fluorine plastics either in the dielectric nor in the jacket and thus provide a robust and environmentally friendly option.
The product series Spuma, S and SX provide lowest attenuation, high flexibility and optimal shielding. Products from the Spuma series are similar to the LMR® products from Times Microwave. The series with LSFH jacket material and the radiation crosslinked SX series with the RADOX® jacket offer extremely high flame protection.
HUBER+SUHNER MBX/MFBX/MMBX connectors are especially developed for board-to-board and board-to-module RF interconnections. The mechanical design is outstanding, allowing the MBX/MFBX/MMBX to cope with mechanical misalignment in radial and axial directions and still hold an excellent electrical performance. These series are the answer to higher integration and miniaturisation. They are the perfect solution for multiple connections from board-to-board and complex stack-ups in radio module applications.
HUBER+SUHNER QMA and QN connectors have a quick-lock coupling mechanism. QMA and QN are easy to mate and allow a high packaging density because no tools are needed.
