Abstract

This paper describes a coherent detection receiver (CDR) with adaptive image rejection capability which is also compatible with existing monolithic integrated optics and MMIC technology. It details the component selection and circuit layout tradeoffs that were considered for the design and fabrication of the CDR in monolithic IC format. An optical `half receiver' IC with waveguides, phase shifter, 3 dB coupler, and balanced mixer diodes has been constructed and tested. Measurements and results for this chip are given and discussed. An initial design and simulated results for the microwave (intermediate frequency) IC are also given and discussed.
