{{Main|RF CMOS}}

RF CMOS refers to [[RF circuit]]s ([[radio frequency]] circuits) which are based on [[mixed-signal integrated circuit|mixed-signal]] [[MOS integrated circuit|CMOS integrated circuit]] technology. They are widely used in [[wireless telecommunication]] technology. RF CMOS was developed by [[Asad Abidi]] while working at [[UCLA]] in the late 1980s. This changed the way in which RF circuits were designed, leading to the replacement of discrete [[bipolar transistors]] with CMOS integrated circuits in [[radio]] [[transceivers]].<ref name="O'Neill">{{cite journal |last1=O'Neill |first1=A. |title=Asad Abidi Recognized for Work in RF-CMOS |journal=IEEE Solid-State Circuits Society Newsletter |date=2008 |volume=13 |issue=1 |pages=57–58 |doi=10.1109/N-SSC.2008.4785694 |issn=1098-4232}}</ref> It enabled sophisticated, low-cost and portable [[end-user]] terminals, and gave rise to small, low-cost, low-power and portable units for a wide range of wireless communication systems. This enabled "anytime, anywhere" communication and helped bring about the [[wireless revolution]], leading to the rapid growth of the wireless industry.<ref>{{cite journal |last1=Daneshrad |first1=Babal |last2=Eltawil |first2=Ahmed M. |title=Integrated Circuit Technologies for Wireless Communications |journal=Wireless Multimedia Network Technologies |volume=524 |date=2002 |pages=227–244 |doi=10.1007/0-306-47330-5_13 |isbn=0-7923-8633-7 |publisher=Springer US|series=The International Series in Engineering and Computer Science }}</ref>

RF CMOS technology is crucial to modern wireless communications, including wireless networks and [[mobile communication]] devices. One of the companies that commercialized RF CMOS technology was [[Infineon]]. Its bulk CMOS [[RF switches]] sell over 1{{nbsp}}billion units annually, reaching a cumulative 5{{nbsp}}billion units, {{as of|2018|lc=y}}.<ref>{{cite news |title=Infineon Hits Bulk-CMOS RF Switch Milestone |url=https://www.eetasia.com/news/article/18112004-infineon-hits-bulk-cmos-rf-switch-milestone |access-date=26 October 2019 |work=[[EE Times]] |date=20 November 2018 |language=en-PH}}</ref>
