Classification: CPC H | IPC H

Claim 0:
1. An integrated device package comprising:
a laminate substrate having a front side and a back side, the laminate substrate comprising a plurality of layers;
an integrated device die mounted to the front side of the laminate substrate, the integrated device die comprising radio frequency (RF) circuitry and having a first impedance, the integrated device die operating at one or more operational frequencies;
a plurality of conductive bumps disposed between the integrated device die and the front side of the laminate substrate, the conductive bumps electrically connecting the integrated device die and the laminate substrate; and
a bump launch structure defined at least in part by one or more layers at or near the front side of the laminate substrate, the bump launch structure comprising metallic and insulating materials arranged in a first pattern having a second impedance that is matched to the first impedance such that a voltage standing wave ratio (VSWR) of the bump launch structure is less than 4:1,
wherein the first pattern of the bump launch structure comprises a metallic trace extending generally parallel to a major lateral dimension of the laminate substrate for transferring signals laterally and comprising at least two turns and a variable width portion along at least a portion of a length of the first pattern of the bump launch structure, the variable width portion of the metallic trace disposed in a same plane as the at least two turns, wherein the variable width portion is positioned between the at least two turns and a conductive via, and wherein the variable width portion is positioned adjacent to a location at which the metallic trace connects to the conductive via.
