A 12.5 dBm output power amplifier (continuous into 50 Omega), a pulse width and rate control circuit and a voltage reference circuit are included on the IC. The pulse-mode 24GHz output signal is modulated via the final stage bias current to achieve a RF carrier leakage of -50 dBm in the off-state. The power dissipation is 360 mW when RF is on, 117 mW when RF is off, resulting in a typical 122 mW dissipation in normal operation. The 1.2 times 0.87 mm2 IC operates from a 4.5 V supply and is fabricated in 0.25 mu m SiGe:C BiCMOS technology [1].","PeriodicalId":356468,"journal":{"name":"2007 IEEE Radio Frequency Integrated Circuits (RFIC) Symposium","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122429766","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}
