38 PRODUCTS Bluetooth/FM radio combo chip meets cost requirements of the mobile phone market delivers stereo FM R(B)DS reception direct to Bluetooth headsets STMicroelectronics has introduced its 4th-generation Bluetooth/FM Radio combo sytem-on-a-chip, which meets the integration and cost requirements of the cellular phone market. By combining Bluetooth wireless personalarea-network functionality with a FM radio transceiver in a single 65-nm chip, the STLC2690 saves both space and cost for manufacturers of portable products For consumers, the device delivers stereo FM R(B)DS reception (RX) direct to their Bluetooth headsets. The fully integrated short range FM R(B)DS transmitter (TX) allows users to enjoy stored music content on any in-car or home FM radio tuner. The short-range FM transmitter is speciﬁcally designed for use in mobile The integrated FM receiver is said to set a new world standard for receiver sensitivity. With real-time programmable ﬁlters for optimum search and sensitivity stability, the STLC2690 can also be used with integrated FM antennas. The device supports all deployed R(B)DS services and all worldwide FM bands (65 to 108 MHz). This chip is manufactured in ST’s advanced low-leakage ultralow-power 65-nm RFCMOS technology. It comes in a wafer-level chip-scale package (WLCSP) with a 0.4-mm pitch. Its ultra-low external bill-ofmaterials (BOM) count allows a PCB footprint as small as 36 mm2. The pin-out arrangement is also suitable for use on lowcost PCB assemblies. www.mwee.com/205918670 phones that also take advantage of a FM receiver. Proprietary SureTune technology automatically selects the optimal FM transmit frequency, while the programmable high output power allows stable operation even when using integrated antennas with poor efﬁciency. The STLC2690 delivers a stable and user-friendly FM transmission implementation with real enhancement of the user experience in mobile applications, comments ST. The STLC2690 is compliant with BT v2.1+EDR and requires only one supply voltage. Current consumption is reduced by up to 35 percent compared to previous generation products in 130-nm technology. Signal generators support broadcast applications instruments are cross-compatible and complementary and support all conventional broadcasting standards A family of signal generators from Rohde & Schwarz — including the SFE100, SFE, and SFU — is all an engineering team needs for development, service, quality assurance, and production of broadcast receiver instruments. To achieve maximum versatility, the instruments are cross-compatible and complementary. All conventional broadcasting standards are supported: analog or digital, terrestrial, satellite, cable, mobile TV, and digital sound broadcasting. The SFE100 test transmitter is a single-standard instrument specifically for production applications. The compact SFE broadcast tester is a versatile and cost-efficient multi-standard generator for a wide variety of applications in the lab, in service, and in the factory. The multi-standard SFU broadcast test system, which offers comprehensive simulation and analysis functions, is a high-end instrument for complex applications in development. The SFE100 is a test transmitter used during the production of broadcasting terminal equipment. It delivers an attractive price/performance ratio and combines an RF signal generator, power amplifier, and baseband generator in a single instrument. As a single-standard test transmitter, the SFE100 is available in several models for all common TV standards and many sound broadcasting standards. It uses real-time coding or operates as an arbitrary waveform generator. Its integrated power amplifier makes the instrument especially suitable for use in production test systems. The SFE100 is an easy to use, costefficient broadcast signal source but it can also be used for special applications as a second RF channel for the SFU. Up to three standards can be installed simultaneously in the SFE broadcast tester. The generator combines an RF modulator, a universal real-time coder, and baseband signal sources in one instrument. In this configuration, it can generate broadcast signals in the frequency range of 100 kHz to 2.5 GHz in real-time. Its modular design makes it ideal for a wide variety of lab applications as well as for service and quality assurance. Because it includes a noise generator and BER tester, the SFE also handles more complex measurement tasks. The SFU broadcast test system is the high-end instrument of the family and can be used to develop and extensively test new digital broadcasting transmission methods. It provides highprecision standard signals, permits signal modifications up to the system limit, and can insert defined errors. The SFU can easily be upgraded to accommodate changes in broadcast standards. It combines a test transmitter, a signal generator/recorder for MPEG-2 transport streams, a fading simulator with up to 40 paths, a broadband digital AWGN noise source, and an ARB generator in a single platform. The SFU is suitable for research and development as well as for quality assurance and EMC measurements. www.mwee.com/205918592 Microwave Engineering Europe ● January/February 2008 ● www.mwee.com 038_MWEE.indd Sec1:38 25/01/08 17:19:41 http://www.mwee.com/205918670 http://www.mwee.com/205918592 http://www.mwee.com
