Currently, MMIC vendors concentrate on improving performance and reducing MMIC cost. Low-cost high-volume modules impose additional requirements relating to MMIC compatibility with module volume production processes. The MMIC design techniques discussed include: circuit compaction, use of external support components, maximizing symmetry, reduction of external connections, compatibility with automatic bonding machines, compatibility with automatic pick-and-place machines, and standardizing RF probe types. General MMIC requirements relative to module needs for both terrestrial and satellite communication links are also discussed.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114786280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a fast solution of such complex electromagnetic problems essential for an efficient design and optimization of high performance antennas under the influence of mobile platforms, MPI-based parallelization strategies are developed.

Also, the bottom ground enables the impedance to be 50 ohm with narrow line width. HGCPWs on the 6-¿m and 30-¿m DAM cavities were fabricated and tested.
