Modular millimetre-wave transceiver design for today digital radio-links

The development of a highly integrated Ka-band (24-26GHz) transceiver module for a high volume point to multipoint telecommunication application is presented. In order to reduce the costs, a full GaAs MMIC solution has been chosen. The module architecture and assembly technology are described. 8 different Ka-band MMICs have been or are being designed and fabricated for this application. The measured performances of the developed MMICs and of the module prototypes are given.
