This paper presents a GaAs VLSI implementation of an efficient table lookup algorithm for 2.5 Gb/s ATM switching systems. This algorithm presents some very promising features such as the number of Virtual Channels which can reach 30000 possible connections. An extra header of three bytes is attached to the cell header which contains policing and priorities information for use inside the switch. Routing information is performed by using the Virtual Path Identifier (VPI) and the Virtual Channel Identifier (VCI) in the incoming cell to access the header translation table. The VLSI chip is fabricated using 0.6 /spl mu/m gate GaAs MESFETs, by VITESSE Semiconductor and it is housed in a 132 pin LDCC package. The Label Translator chip is expected to operate at 311 MHz with an associated power dissipation of 4 W.","PeriodicalId":365997,"journal":{"name":"GaAs IC Symposium IEEE Gallium Arsenide Integrated Circuit Symposium. 18th Annual Technical Digest 1996","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128918763","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}

The S-band receiver MMIC is the first of its kind, integrating a 2-stage HEMT LNA RF amplifier and a HEMT LO amplifier with an HBT double-balanced Gilbert cell mixer using selective MBE. The MMIC achieves greater than 18 dB conversion gain over an RF input band from 1.4-2.6 GHz, a minimum DSB noise figure of 2.3 dB and an IF3 of -0.5 dBm with no IF amplification. In addition, LO-IF and RF-IF isolations in excess of 22 dB and a 2-2 Spur suppression of 40 dBc are obtained due to the use of the double balanced HBT Gilbert cell mixer. The compact MMIC is 7.7/spl times/2.9 mm/sup 2/ and is self-biased from /spl plusmn/5 V supplies with a total dc power consumption of 735 mW.
