RX-TX analog front-end module with 2 × 96-channels for mm-wave imaging systems

Active millimeter-wave imaging systems are increasingly utilized in security, medical and industrial applications. At E-Band frequencies, such systems integrate more than three thousand antennas on 2 m × 1 m aperture. Commercial success of those systems requires cost efficient but precise manufacturing technologies to build highly integrated modular mm-wave front ends. Here, a module for a new sparse imaging array architecture is presented. The module is manufactured using a unique mm-wave chip-on-board technology. It operates from 70 GHz to 80 GHz, and integrates 48 MMICs and several thin film ceramic components.
