MMIC Technology in Japan for the Last Mile
This paper presents the overview of MMIC technologies in Japan for the wireless communication systems. Device and process technology status in the microwave and millimeter-wave frequency range are shown. Especially, for multimedia wireless communications, millimeter-wave systems are advantageous because of wide bandwidth, fine beam forming, compact size and so forth. A 60GHz-band MMIC chip set for short range wireless communication systems and compact multi-chip transmitter/receiver modules have been demonstrated. Their features are the use of 60GHz-band dielectrically stabilized fundamental oscillators and wideband power amplifiers. Furthermore, high reliability millimeter-wave MMIC technology has been developed, and 3 dimensional master-slice MMIC approach has been proposed and demonstrated toward low cost and mass production.
