A front-end MIMIC (millimeter wave monolithic integrated circuit) with a 4:2 MUX/DEMUX (multiplexer / demultiplexer) functionality for 60 GHz transceiver with multiple antennas has been developed. The chip has been realized using 100 nm gatelength metamorphic InAlAs / InGaAs HEMT (high electron mobility transistor) technology on GaAs substrate together with CPW (coplanar waveguide) technology. The chip has been designed for functionality over the frequency range of 55 - 65 GHz. The novel topology for the MIMIC will be described. The single building blocks and details for the DPDT (double pole double throw) switch design will be explained, simulated and measured results will be compared. Finally, the overall performance for the integrated chip will be presented.
