Abstract :
A transceiver MIMIC (millimeter wave monolithic integrated circuit) with four antenna ports functionality for 55 to 65 GHz wireless multimedia applications 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 GCPW (grounded coplanar waveguide) technology. The novel transceiver topology for the MIMIC is described. The different building blocks, namely the 2:4-switch design, sub-harmonic IQ-resistive mixer and variable gain amplifiers, are explained in details. Simulated and measured results are compared. Finally, the overall performance for the integrated transceiver chip is presented.
