San Francisco, CA (06/12/2006) - At the MTT Wireless Conference in San Francisco, June 13 – 16, booth 2209, Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing solutions, will highlight some of the technologies that enable wireless consumers to enjoy more features, faster delivery of data services, and fewer dropped calls. The continued demand for cellular handsets and the increasing popularity of new functions—such as text messaging, downloadable ring tones, cameras, music players and television—has led to a corresponding demand for base stations that can process multiple wireless standards, handle the complex modulation requirements of 3G systems, accommodate several input and output sources in smart antenna systems, and offer increased coverage per tower. ADI’s wireless infrastructure solutions help define the user experience by accurately and efficiently amplifying, converting, and processing the signals and by delivering, in real-time, enhanced sound, images and data to the end-user.

“High-performance ICs from ADI can be found almost everywhere in the wireless infrastructure signal chain—from the analog radio frequency (RF) front end to digital signal processing,” said Peter Real, product line director, RF and Networking Components, Analog Devices. “Cellular phones are evolving from voice-only communication devices to multimedia terminals with complex audio, imaging, and data processing functions that can be used anywhere in the world, and technologies such as WiMAX are creating new options for high-speed wireless connectivity. ADI is enabling these market shifts with continuous investment in a strong portfolio of proven solutions that address the cost, functionality, performance and reliability requirements of advanced wireless infrastructure technologies.”

In booth 2209 of the MTT wireless conference, ADI will display a variety of RF technologies, including wireless infrastructure solutions designed to handle the complex signal processing challenges of current and next-generation base stations for single or multicarrier, direct conversion or superheterodyne radio designs.

ADF4108, Industry’s First 8 GHz PLL
Introduced today, the ADF4108 is the industry’s first 8 GHz phase-locked loop (PLL) synthesizer. The device can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters in high-frequency wireless systems. Because of its high-frequency operation, the ADF4108 can eliminate the need for frequency doublers, thereby simplifying the system architecture and reducing system cost.

Quadrature Modulators Support all Wireless Standards
ADI will highlight the newest members of its portfolio of quadrature modulators including:

  • 50 MHz to 2.2 GHz RF/IF quadrature modulator – announced today, the ADL5385 quadrature modulator operates from 50 MHz to 2200 MHz, making it well-suited for low intermediate frequency (IF) and RF applications such as broadband wireless access systems, microwave radio link transmitters, cable modem termination systems and cellular infrastructure. For more information, please visit
  • Family of 250 MHz to 4 GHz quadrature modulators – recently introduced, the ADL537x family of five pin-compatible quadrature modulators enable wireless system engineers to standardize board designs across multiple operating bands and cellular standards and features a direct interface to ADI’s family of TxDAC+® transmit digital-to-analog converters. Each of the five quadrature modulators is optimized for a specific frequency band. For more information, please visit

    Matching Pre-Driver Amplifiers
    Recently announced, the ADL5322 and ADL5323 are highly linear, fixed-gain RF amplifiers that integrate matching networks on a single chip. The ADL5322 and ADL5323 are ideally-suited for use with ADI’s ADL537x family and ADL5385 quadrature modulators to provide a highly linear, compact transmit signal path.

    Two-Channel Logarithmic Detector Delivers Accurate Power Measurement and Control
    Announced today, the ADL5519 is a dual logarithmic detector that precisely measures and controls the gain across the transmitter and receiver signal path. The device integrates two matched logarithmic detectors on a single chip and covers a wide frequency range of 1 MHz to 10 GHz. For more information, please visit

    Design Tool Speeds Time-to-Market
    Removing time-consuming iterations from the design process, the recently introduced ADIsimPLL™ Version 3.0 is the latest generation of ADI’s successful PLL circuit design and evaluation tool, and is a member of ADI’s portfolio of RF development tools, which includes the ADIsimADC™, ADIsimCLK™ and ADIismLINK™. Offered as a free download on the ADI website, ADIsimPLL provides a comprehensive PLL design and simulation package for Analog Devices’ range of PLL frequency synthesizers, enabling rapid prototype development and design optimization.

    Reducing the Complexity of Frequency Synthesis
    Demonstrating its leadership in direct digital synthesis (DDS) technology, ADI is exhibiting a 500 mega-samples-per-second (MSPS) DDS device with an integrated 10-bit digital-to-analog converter (DAC). The AD9911 is ideal for multi-tone modulation as it allows designers to internally mix DDS signals digitally prior to analog conversion and modulate frequency, phase and amplitude. The AD9911 can significantly ease the need for frequency planning, thus enabling designers to more easily achieve optimum dynamic performance in the high end of the frequency range.

    Low-Power, Single-Chip RF ICs Enable Short-Range Wireless Connectivity
    In addition to highlighting wireless infrastructure solutions, ADI will demonstrate its flexible, highly-integrated ADF7012 single chip VHF/UHF transmitter IC, which addresses the need for low-rate wireless connectivity. The ADF7012 features 50 MHz to 1 GHz frequency operation, allowing multiple frequency plans to be implemented for transmit applications including RF remote controls, remote keyless entry and wireless sensor applications.
