PRODUCTS 29 TV and radio CMOS RF tuner combines ultra low power silicon design with 130-nm CMOS process A low power DVB-T/H terrestrial broadcast radio frequency (RF) tuner, the E4000 from Elonics consumes 105 mW in continuous mode and 13 mW in time sliced mode. It uses a combination of ultra low power silicon design techniques along with state-of-the-art 130-nm CMOS process technology. The CMOS tuner easily surpasses the MBRAI 2.0 requirements for mobile devices and NorDig 2.0 for DTV applications. The E4000, which has an RF input frequency range from 64 MHz to 1700 MHz can be re-conﬁgured under software control to support additional broadcast standards in the VHF, UHF and L bands. This is important for digital TV as there is a profusion of standards across the world. It means that manufacturers can use a single tuner across the globe, allowing them to cut development time and costs. The tuner supports DVB-H, T-DMB, and CMMB (China) mobile digital TV standards; DVB-T, D-TMB, ISDB-T 13 Seg, and ATSC terrestrial digital TV standards; and legacy FM standards. Designed to interface directly to a digital demodulator, the E4000 has a fully integrated low noise ampliﬁer (LNA), programmable RF ﬁlter, and an RF mixer providing superior real world performance. The wide tuning range of the synthesiser and the programmable IF channel ﬁlter allows the user to cover a very wide frequency spectrum and different broadcast channel bandwidths. The E4000 tuner uses a zero IF architecture, which dramatically reduces the number of external components required and ensures that the device is suitable for high volume consumer applications. The launch of Elonics ﬁrst standard product, the E4000 CMOS tuner represents the ﬁrst use of a proprietary innovative technology called DigitalTune™. DigitalTune is a patent pending radio frequency architecture that uniquely allows each stage of the RF signal processing to be adjusted under digital control. This strategy has a number of beneﬁts over traditional tuners that typically use analogue control voltages to manage the RF signal gain. As well as providing superior ﬂexibility, it is used to adjust the performance of the tuner for optimum linearity or noise ﬁgure according to signal conditions. www.mwee.com/212901923 Microwave Engineering Europe Upcoming features and article focus March 2009: Wireless Infrastructure Radio (and SDR) April 2009: Antennas MMICs/RFICs May 2009: Short Range Wireless GPS & Satellite June 2009: Military/Aerospace RF Ampliﬁers July/August 2009: Low Power RF CAD/EDA MTTS 2009 Report Microwave Engineering Europe ● January/February 2009 ● www.mwee.com http://www.mwee.com/212901923 http://www.filter-solutions.com http://www.filter-solutions.com http://www.mwee.com
