Design and Measurement of D-Band Bonding-Wire Interconnection on Quartz Glass Substrate

This paper presents a D-Band wire bond interconnect method for low-cost, wide bandwidth transmission on quartz glass substrate. A novel compensation technique for bonding-wire interconnection based on single-objective optimization is proposed. This design has a conductor-backed coplanar waveguide (CB-CPW) structure and precisely modeled bonding-wire. The compensation structure based on single-objective optimization has achieved a good impedance matching in the D-band, and the measurement results demonstrate that relative bandwidth of -10 dB reflection can be achieved about 16.4%.
