Atmel Targets Wireless Infrastructure Applications with Introduction of New High-Performance SiGe Up-Conversion Mixer ICs.Business Editors/High-Tech Writers HEILBRONN, Germany--(BUSINESS WIRE)--June 10, 2003 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the availability of three new active up-conversion mixer ICs for cellular and WLL See wireless local loop and PHS-WLL. infrastructure, instrumentation and ISM band applications. The new devices ATR ATR Achilles tendon reflex, see Ankle reflex 0785, ATR0786 and ATR0787 are part of Atmel's product line of essential building blocks for the main RF standard functions, including mixers, modulators and demodulators. These building blocks can be used for multi-purpose applications in RF systems including wireless access systems (such as point-to-point or point-to-multipoint radio systems) and base stations. Unlike most conventional mixers which are passive solutions and have a higher risk of spurious emissions, these new devices are active components, providing a conversion gain of about 17 dB, for drastic reduction of external influences. Moreover, spurious emissions can be reduced since the new devices incorporate buffers (e.g. LO buffer) in contrast to passive solutions. The ATR0785, ATR0786 and the ATR0787 are manufactured using Atmel's advanced Silicon Germanium (SiGe) process enabling maximum performance. Atmel's innovative SiGe process also ensures that the devices are thermally insensitive. This feature makes them highly reliable and guarantees maximum quality. Each up-converter is dedicated for a specific operating frequency to ensure a highly linear IF-to-RF conversion with low LO-RF leakage. The ATR0785 covers the 800 to 1000 MHz operating range and is therefore optimized to be implemented into GSM, TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). , and CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. applications, whereas the ATR0786, operating at 1800 to 2100 MHz, is well-suited for use in UMTS (Universal Mobile Telecommunications System) The GSM implementation of the 3G wireless phone system. Part of IMT-2000, UMTS provides service in the 2 GHz band and offers global roaming and personalized features. , DCS (1) See also DSC. (2) Digital Cross-connect System) A network switching and grooming device used by telecom carriers. See digital cross-connect. or PCS systems. The ATR0787 can be used for any wireless application in the 2100 to 2500 MHz band. All I/O ports have a 50 Ohm impedance. The LO and the RF ports can also be driven single ended if needed, thus helping to simplify the application. This allows easy and fast design-in while keeping the board space consumption to a minimum. "With these up-conversion mixer ICs, we offer designers of wireless infrastructure systems an easy-to-implement solution with perfect performance and reliability. Along with our earlier introduced down-coverter family, Atmel extends its RF building blocks product range to provide customers a wide set of multiple solutions," stated Carsten Friedrich, Marketing Manager for Cellular RF Applications. Samples of the ATR078x (TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package 16 package) are available now. Pricing starts at US$ 3.85 (10 k).
