Editing Software-defined radio (section)

=== 2000s ===
The SpeakEasy SDR system in the 1994 uses a [[Texas Instruments TMS320|Texas Instruments TMS320C30]] [[CMOS]] [[digital signal processor]] (DSP), along with several hundred [[integrated circuit]] chips, with the radio filling the back of a truck. By the late 2000s, the emergence of [[RF CMOS]] technology made it practical to scale down an entire SDR system onto a single [[mixed-signal]] [[system-on-a-chip]], which [[Broadcom]] demonstrated with the BCM21551 processor in 2007. The Broadcom BCM21551 has practical commercial applications, for use in [[3G]] [[mobile phones]].<ref>{{cite conference |last1=Leenaerts |first1=Domine |title=Wide band RF CMOS circuit design techniques |url=https://ewh.ieee.org/r5/denver/sscs/Presentations/2010_05_Leenaerts.pdf |conference=[[IEEE Solid-State Circuits Society]] Distinguished Lecturers Program (SSCS DLP) |publisher=[[NXP Semiconductors]] |date=May 2010 |access-date=10 December 2019}}</ref><ref>{{cite web |title=Broadcom ships "3G phone on a chip" |url=https://linuxdevices.org/broadcom-ships-3g-phone-on-a-chip/ |website=The LinuxDevices Archive |access-date=12 December 2019 |date=16 October 2007}}</ref>
