RF and Microwave Symposium

RF and Microwave Symposium

In this free, full-day seminar, hosted by National Instruments and AWR, attendees can choose between two tracks, either focusing on mobile and wireless communications or microwave, radar, RF and signal intelligence. Attendees will learn how to implement phase-coherent MIMO systems, configure record and playback systems, optimise power amplifier designs and radar systems, and introduce real measurements alongside simulation in the design process.

    Keynote: AWR Roadmap: Trends, Products and Markets

    This presentation begins with a brief introduction to the AWR Design Environment™ and the powerful, innovative technologies contained within the latest release of AWR’s RF/microwave design software.

    Keynote: Applying Modular Instrumentation to Reduce the Cost of Test

    Synthetic instrumentation can lower the total ownership cost of test by reducing the number of legacy instruments needed, aiding in the insertion of new technology during the life cycle and reducing sustainment costs. Explore how you can use the modular, software-defined RF platform from NI to achieve these goals.

    Optimising IM3 and ACP Measurements

    Intermodulation distortion (IM3) and measurements such as adjacent channel power (ACP) have long been highly important, yet often misunderstood, figures of merit that describe the linearity of an RF component or system. Learn what these measurements describe, relating the characterisation of third-order distortion products to linearity and spectral regrowth of modulated signals.

    Advanced VNA Measurements

    Receive an introduction to the SOLT calibration technique. In addition, explore advanced vector network analyser (VNA) measurement techniques such as dual sources in frequency offset mode, time domain analysis and source loops for pulsed S-parameter measurements.

    Digital Predistortion (DPD) Design-to-prototype Framework for Power Amplifiers

    Putting together a DPD system is an expensive and a complex task. RF circuit design, digital interface, DPD algorithms, measurements and their interaction need to be understood. In this presentation, we show an integrated solution that combines the power of AWR and National Instruments platform as an ideal place to design, test, measure and prototype all the critical engineering required for DPD system development.

    Under the Hood of 802.11ac and LTE

    Review some of the key technology enhancements introduced in new standards such as IEEE 802.11ac and LTE. Learn key differences between existing 802.11a, b, g, n and ac standards and some of the key test challenges introduced by both standards.

    Frequency Planning for Wireless Systems Design

    AWR’s radio frequency planning tool, RFP™, is an essential analysis tool when developing radio communications systems. RFP enables designers to effortlessly and efficiently determine spurious free bandwidths in RF/microwave designs. RFP gives engineers a greater insight into unwanted signals or spurs generated in a specified bandwidth. The RFP RF link can consist of parts such as amplifiers, mixers and filters, and can be built up from a selection of commercially available parts or behavioural models.

    Rapid Prototyping with Software Defined Radio in LabVIEW

    Software defined radio (SDR) offers an affordable and flexible way to prototype new algorithms faster, thereby shortening time to results. NI LabVIEW delivers an ideal platform for exploring algorithms and rapidly prototyping a wireless communications system. At this session, we examine a broad range of SDR applications from simple record and playback to advanced MIMO prototyping and next generation protocols.

    Design and Simulation of RADAR Systems and Phased Arrays

    Modern radar system analysis needs to account for both the performance of the electronic system as well as modeling the target in its environment. Many modulation types are available to the radar system designer such as short pulse, long pulse, ICWFM, short and long pulse Chirp. Each modulation type is associated with different radar modes, for example short range target tracking, track while scan, target illumination, etc. This presentation will outline the use of AWR’s Visual System Simulator™ (VSS) and its newly released Radar Library with demonstration examples.

    A Comprehensive DC to Microwave/RF Design Flow With AWR Software and NI Multisim

    The Microwave Office design environment is well suited for higher-frequency designs and when combined with the NI Multisim circuit simulation software, low-frequency circuit functionalities are added for an even more complete circuit design flow (DC up through microwave/RF). NI’s Ultiboard printed circuit board (PCB) layout software is capable of integrating high-frequency circuit layouts with Multisim, enabling designers to rapidly create a layout of a complete prototype, add mechanical and graphical shapes to the design, create 3D views of the final design and export standard fabrication files.

    Introduction to Spectrum Monitoring Receivers

    Spectrum monitoring receivers are signal analysers designed to capture off-the-air signals and demodulate them. Learn how spectrum monitoring receivers can separate a signal of interest from high-power interferers using preselection and IF-roofing filters. See how you can use FPGA-based technology in real-time signal processing and demodulation.

    Design and Optimisation of 3D Connectors

    The most recent addition to AWR’s EM simulation tool portfolio is Analyst™, a full 3D FEM-based EM solver. It has been integrated into Microwave Office® much like AWR’s 3D planar analysis tool AXIEM®, so the user need not be an EM tool expert to make use of this novel technology. In this presentation a task of optimisation of coax-to-microstrip transition at a specified design frequency will also be discussed in detail. The goal is to maximise transmission of energy from coax TEM mode into microstrip quasi-TEM mode, and some common tricks to achieve that goal will be demonstrated.

    Design Methodology for GaAs MMIC PA

    This presentation showcases the design of a high power, two stage, 1 Watt, X-band MMIC amplifier using one of the more common design methodologies in use today, the Cripps linear power estimation method. The design is carried out in AWR’s Microwave Office software, which has a number of useful features for aiding in the design and layout of the circuit, including advanced control of the schematic and layout and EM simulation of large portions of the matching networks. These tools reduce errors substantially by the time LVS is carried out after the design process is complete.

    PoweRFul Microwave: Modeling a VHF Balun with AXIEM

    One route to high efficiency amplifiers is to construct a balanced design. In this topology the two ‘halves’ are driven 180° out of phase; the structures that create these phase shifts are traditionally called Baluns – BALanced to UNbalanced. Commonly these are constructed from coaxial cables often incorporating ferrites; an alternative approach using planar transmission lines has cost and assembly advantages, but has suffered from being difficult to design, partly due to a lack of adequate suspended stripline models. This paper sets out an approach using AWR’s AXIEM 3D planar EM simulator which can quickly and accurately design such dividing and combining structures.
