Abstract
A connection assembly includes a coaxial cable to microstrip flexible circuit connector and a mating microstrip flex circuit to electronic circuit connector. The coaxial cable to microstrip flex circuit connector comprises a portion which is mechanically attached to the coaxial cable and a portion which is mechanically attached to the microstrip flex circuit. The coaxial cable attachment portion includes a first electrical connector electrically connected to the center conductor and a second electrical connector electrically connected to the shielding conductor of each coaxial cable. The microstrip flex circuit attachment portion includes a third electrical connector electrically connected to each trace and a fourth connector electrically connected to the ground plane conductor. The flex circuit to electrical circuit connector comprises a plurality of unsupported extensions of a trace or the ground plane conductor. The extensions are electrically connected to connection pads of a printed circuit board of an electronic circuit by a surface connection, and can be bent to opposite sides of the electronic circuit to reach connection pads on a printed circuit board.
