System-level integrated circuits for phased array antenna applications

A new, high-density microwave circuit has been developed for use in advanced communication system antennas. These System-Level Integrated Circuits, or "SLICs", include integral features and functions facilitating reliable operation, improved performance, and ready application. An optical fiber feeds both control and 20-GHz RF signals to an 8-element phased array module, wherein SLIC circuitry provides automatic gain control, thermal compensation, voltage regulation, control signal processing, and health/status feedback. Modules have been fabricated using the new SLIC MMICs and the Microwave High Density Interconnect (MHDI) multilayer lamination process.
