Tyco Announces Compression Coax Board-to-Board RF Connector Series

Harrisburg, PA -- Tyco Electronics has introduced a new low-profile microminiature RF interconnect for direct board-to-board connections.

Traditionally, board-to-board RF connections have been achieved by using either two cable connectors or two connectors with a third, spacer or bullet, between. Tyco Electronics' Compression Coax Board-to-Board Blindmate, which consists of a single piece connector with spring-loaded contact, is initially available in three different lengths for board spacing of 6.65 mm, 10 mm, and 14 mm. One side of the connector is soldered on the board surface and the other side is mated directly on top of the opposite target board (see cross section diagram below). The product is supplied in trays for pick and place compatibility. The connector has an operating temperature range of –40 to +125°C, an impedance of 50 Ohms, and can operate effectively at frequencies up to 4 GHz. Return loss is specified as a minimum –20 dB at frequencies up to 2.1 GHz.

Tolerance against axial misalignments from the nominal board stacking height is specified as ±1.0 mm for the 10 mm and 14 mm versions, and ±0.3 mm for the 6.65 mm version. Tolerance against radial misalignment is specified as ±0.8 mm from centerline in any direction for all three versions. Typically contacting a gold-plated PCB target, the target pads can also be tin plated, or a gold-plated disc can be applied to the mating PCB for improved characteristics. Additional sizes can be developed to customer request.
