High performance connector contact structure
First Claim
1. An electrical connector module, comprising:
- a lead frame providing a coplanar waveguide structure, the lead frame comprising;
a plurality of signal conductors; and
a plurality of ground conductors adjacent to the signal conductors,wherein;
the ground conductors are wider than the signal conductors; and
each of the plurality of signal conductors comprises a mating contact portion having a planar portion and a beam portion with a first contact surface on the planar portion and a second contact surface on the beam portion.

Abstract
An RF connector module and associated printed circuit board providing high isolation and controlled impedance at RF frequencies. The connector module may be manufactured using conventional manufacturing techniques, such as stamping, insert molding, multi-shot molding and interference fit between components, to provide low cost. A connector module constructed with these techniques may implement a co-planar waveguide structure, with conductive shields for isolation and lossy material to enforce co-planar propagation modes. The printed circuit board may similarly be manufactured using conventional manufacturing techniques, including drilling to form vias. As a result, an interconnection system may be manufactured with low cost. These techniques may be applied to provide performance, including in the form of isolation between RF signals, comparable to that provided by more expensive components.
