This article is part of our IMS2022 coverage.
At Analog Devices’ IMS2022 home base, Booth 3050, attendees can take advantage of a wide-ranging program of educational MicroApps, workshops, and demos. The casual sessions will cover issues at the device, circuit, and system levels, including recommended test methods.
ADI provides four in-booth, 15-minute-long MicroApps presentations preparing circuit and system designers for the increasing frequencies of communications and radar applications with their increasing data rates. During the opening morning of the IMS exhibition, ADI Product Application Engineer Kudret Unal presents the first MicroApp on Tuesday, June 21, from 11:15 am to 11:30 am, “Is it Difficult to Synchronize Fractional PLLs? Not Anymore.” Anyone concerned with minimizing jitter in PLL arrays, such as in 5G wireless networks, will find this time well spent.
On Wednesday, ADI Product Applications Engineer Kieran Barrett shows how integrating four narrow frequency bands in a single package can reduce phase noise compared to trying to cover the full frequency range in a single wide frequency band. His MicroApp, “Fast Switching, High Performance PLL and Quadband VCO Frequency Synthesizer,” features a unique quadband IC with integrated active filtering for phase-critical applications. It is scheduled for Wednesday, June 22, from 12:45 pm to 1:00 pm.
Later on Wednesday, ADI Product Applications Engineer Eric Carty addresses designers faced with high-speed switching needs, with a quarter-hour lesson on how high-level integration can yield a single-pole, double-throw (SPDT) switch capable of frequency coverage from DC to 34 GHz and data rates to 64 Gb/s. The MicroApp, “DC to 64 Gb/s Micro Relay with Integrated Driver, A Simplified Solution to Increase Productivity,” highlights switching circuitry based on MEMS and CMOS technology and with integrated driver circuitry. It is scheduled for Wednesday, June 22, from 4:45 pm to 5:00 pm. For the final MicroApp, Kudret Unal returns Thursday morning, June 23, from 10:45 am to 11:00 am with “Need Sub-10-fs RMS Jitter Signal Generation Translation Loops” on the challenges of minimizing jitter in frequency translation loops for test/measurement, communications, and other applications, even when striving for jitter levels as low as 10 fs.
ADI will also offer a strong collection of keynote presentations and workshops at 2022 IMS. The keynote, by Systems Application Manager Mike Jones, “Calibrating RF/Microwave Front Ends in Multichannel Receiver and Transmitter Systems,” is scheduled for Thursday morning, June 23, from 8:00 am to 8:20 am. It provides experimental results on the use of hard DSP blocks, ADCs, and DACs integrated within a single IC and how such integration can simplify transmit/receive system layouts.
Workshops include shorter lessons as well as half- and full-day sessions. Prior to the opening of the IMS exhibition hall, on Monday June 20 from 3:35pm to 4:25pm, ADI vice-president, aerospace and defense, Bryan Goldstein shares insights in the development of an RF/microwave transmit/receive system from concept to production in an “RF Boot Camp.” The short course explains how the electrical and mechanical requirements are established for each component based on meeting performance and environmental requirements and how several types of packaging, such as miniature SMT packages, can play a role in the final design and production. Additional ADI workshops at the 2022 IMS cover phased arrays for satellite communications (satcom) systems, development of phased-array systems for communications and radar, and the development of mmWave frequency up/downconverters.
Last but not least, ADI’s demos at IMS2022 booth #3050 illustrate practical implementations of concepts presented in MicroApps or workshops, such as synchronized fractional PLLs and quadband VCO synthesizers. ADI’s demonstrations explore various technical areas, including aerospace, communications, instrumentation, and RF power. Visitors to the booth can learn about optimizing RF signal power, about beamforming at X-band frequencies, implementing mmWave radios for 5G small cells, and using narrowband and wideband signals from 30 MHz to 6 GHz in frequency-agile, software-defined-radios (SDRs).
Of special interest to those with test duties will be ADI’s demonstration of a PC/software-based vector network analyzer (VNA). The modular unit is a fraction of the size and cost of traditional VNAs and reaches a top frequency of 20 GHz.
