MTT-S 2007: Analog Devices Expands RFIC Portfolio With 14 New Products
In addition to the booth demonstrations, ADI will present a discussion on PLLs and short range devices at various times throughout the day at the Avnet booth, #1623. DDS and clocks will be highlighted also at Avnet booth, #1623 throughout the day on Tuesday and Wednesday.
The products introduced at this year's MTT-S International Microwave Symposium include:
RF Amplifiers: The four RF amplifier product families Analog Devices is introducing include LNAs (low-noise amplifiers), IFAs (intermediate frequency amplifiers), driver amplifiers, and RF gain blocks. Each amplifier family is fully specified for operation over temperature, supply voltage and operating frequency, thereby easing the selection and design-in process. Within each RF amplifier family, Analog Devices optimized the performance to cover both broadband and narrowband applications with the minimum number of external passive components.
ADF4113HV PLL Synthesizer: ADI claims this new RF IC is the industry's first PLL synthesizer with a high-voltage charge pump, which extends the power supply voltage up to 16.5 V, compared to most PLL synthesizer ICs which are limited to 5 or 6 V. This extended voltage provides a wider tuning range for broadband frequency synthesis and can be used for the design of products such as private mobile radios (PMR) and communications test equipment. With the ADF4113HV, a high voltage VCO (voltage-controlled oscillator) can be controlled directly through a passive loop filter, eliminating the need for active loop filters. The new PLL joins Analog Devices' PLL synthesizer portfolio, which serves applications such as wireless base stations, mobile handsets/PDAs, broadband wireless access, industrial and instrumentation, test equipment, and satellite equipment.
AD9912 DDS Synthesizer: Targeted at test and measurement equipment, wireless base stations, and secure communications devices, Analog Devices' AD9912 DDS provides analog and mixed-signal engineers with a new level of SFDR (spurious-free dynamic range) performance through the integration of spur-reduction technology. The AD9912 helps ease design efforts and enables engineers to spend less time frequency planning, especially in applications such as military receivers where every last dB is important to maintain critical system functions. The spur reduction capability expands the benefits of DDS into designs where previous wideband SFDR performance was a limiting factor. The new level of performance provided by the AD9912 is attainable using the spur-reduction channels to knock down the two largest harmonic spurs by up to 10 dB. Used in a wide range of applications from test and measurement equipment to wireless and satellite communications, ADI's complete DDS solutions employ an on-chip high-performance DAC (digital-to-analog converter) to convert a reference frequency to a sampled sine wave with extremely fine frequency control.
RF Design Tools Simplify Product Development
Analog Devices offers a number of complementary tools that enable rapid RF prototype development and design optimization. The ADIsimPLL development tool is available to designers at no cost and offers a comprehensive PLL design and simulation package for ADI's range of PLL frequency synthesizers. Additionally, ADI has a range of evaluation boards equipped with driver software to design, optimize, and evaluate new PLLs. Analog Devices also offers the ADIsimDDS, which supports ADI's broad DDS portfolio by assisting users in selecting, evaluating and troubleshooting DDS ICs. The ADIsimDDS tool, which is accessible in real-time and does not require a software download, uses parametric data to mathematically model the general behavior of a selected DDS IC. Analog Devices also offers a range of DDS evaluation boards that consist of a PCB, software and documentation to facilitate bench analysis of the performance of the device.
