Ultra wideband frequency division multiplexing millimeter-wave multi-port receiver analysis

A new millimeter-wave multi-port receiver is analyzed in this paper. Frequency division multiplexing scheme based on four QPSK modulated sub-channels is used to reach 2 Gb/s data-rate. This implementation is validated using advanced system simulations of a short-range 60 GHz wireless link. The receiver model is built using a millimeter-wave multi-port interferometer model based on S parameter measurement results of ultra wideband circuits, fabricated on very-thin ceramic substrate. Bit error rate results are presented and discussed. They prove that the proposed wireless link can be successfully used for an uncoded HDTV transmission up to 10 m range.
