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. Both of these options can add significant cost and assembly time. Tyco Electronics introduced a new low profile, single connector, micro-miniature RF interconnect. The Compression Coax Board-to-Board Blindmate product eliminates the need for these multiple connectors 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 un-mating.
This product is available in three different lengths for board spacing of 6,65 mm, 10 mm and 14 mm. The connector has an impedance of 50 Ω, and can operate effectively up to 6 GHz. Return loss is -20 dB (min) at up to 2,2 GHz.
