A new low-profile single-connector microminiature RF interconnect aims to meet the growing demand for direct board-to-board connections.
Tyco Electronics has developed a new low-profile single-connector microminiature RF interconnect to meet the growing demand for direct board-to-board connections Traditionally, board-to-board RF connections have been achieved by using either two cable connectors or perhaps two board connectors with a third, spacer or bullet, between

Card edge connector meets PCI Express needs
Tyco Electronics has designed a 1mm centreline card edge connector to meet the high performance point-to-point full duplex I/O bus standard for PCI Express architecture.
Backplane connectors boost speed and density
The quest for higher signal speed and density in backplane applications has resulted in the new Z-Pack Max connector from Tyco Electronics.
Both these options can add significant cost and assembly time.
Tyco Electronics' new Compression Coax Board-to-Board Blindmate product eliminates the need for these multiple connectors - and their added cost - by offering a single connector assembly with spring-loaded contact.
One side of the connector is soldered on the base circuit board surface and the other side mates directly on the opposite target board using applied spring pressure.
This "one piece" design offers an easy connection with large radial and axial misalignment, and eliminates the risk of breaking soldered connections when mating or unmating.
This product is initially available in three different lengths for board spacing of 6.65, 10 and 14mm, and is supplied in trays for easy pick and place compatibility.
The connector has an operating temperature range of -40 to +125C, impedance of 50ohm, and can operate effectively at frequencies up to 6GHz.
Return loss is specified as a minimum -20dB at frequencies up to 2.1GHz.
Tolerance against axial misalignments from the nominal board stacking height is specified as +/-1.0mm for the 10 and 14mm versions, and +/-0.3mm for the 6.65mm version.
Tolerance against radial misalignment is specified as +/-0.8mm from centreline, in any direction, for all three versions.
The target pads, typically contacting a gold-plated PCB target, can be tin plated, or a gold-plated disc, also available from Tyco Electronics, can be applied to the mating PCB for improved characteristics.
Additional sizes can be developed to customer request.
With the launch of this single connector design, Tyco Electronics offers customers the opportunity to achieve a high quality, low profile board-to-board connection with fewer piece parts and a lower applied cost than existing competing solutions.
