Monolithic Silicon-Glass Double Balanced Mixers for Wireless [复制链接]

This paper describes the design, fabrication, and performance  of  monolithic  double  balanced mixers designed for cellular applications at 900 and 1800 Mhz. The mixers have been fabricated using a process which combines silicon and glass to form a heterolithic microwave rote.  The  glass  providesd circuit substrate for RF or microwave passive low  loss structures, while the silicon pedestals embedded in the glass allow the formation of Schottky barrier diodes and vias.   The  resulting  circuits  have  levels  of performance similar to those of hybrid double balanced  mixers,  but  are  small,  low  cost, monolithic die suitable for assembly in a low cost plastic package.
