Understanding mechanical tolerances, coaxial design details and connector materials used in cable assemblies helps
produce communications equipment with the lowest levels of passive intermodulation (PIM).
This paper discusses the setup details for the demo shown in this video Head to Head: NI 5665 vs. Traditional Boxed Instruments. The demo compares the performance and speed of the NI PXIe-5665 with the Agilent PXA. Rather than comparing the datasheet specifications of both instruments, this video compares the two instruments while performing real- world test scenarios.
RF laterally diffused MOS (LDMOS) is currently the dominant device technology used in high-power RF power amplifier (PA) applications for frequencies ranging from 1 MHz to greater than 3.5 GHz. This paper will include device and design considerations that specifically target enhancing ruggedness performance. The features of the products using this platform will also be presented.
Considered problem is the reading of multiple RFID tags in the region of space, which is bounded by metal walls and has resonant radio-engineering properties. Obtained results show that it is possible to get reliable automated monitoring of items with tags by forming of a local electromagnetic field (EMF) with the help of slow-wave structures (SWS).
Electromagnetic (EM) simulation is an indispensable tool for characterizing the on-chip passive structures found in radio-frequency integrated circuit (RFIC) designs. However, when it comes to full-chip analysis, the diversity of structure geometries and scale pose a significant challenge for any single EM simulation technology. Successful characterization of an RFIC generally requires three different types of simulators: parasitic extraction, planar EM, and full (arbitrary) 3D solvers.
Engineers often source instruments from different suppliers and mechanical, electrical and software compatibility is essential for successful operation. Get the application note which provides tips on how to select everything from PXI modules to software to ensure compatibility.
With customer requirements and expectations shaping the design process, driven by added complexity as wireless infrastructures evolve, you must assess several factors before designing new RF filter products. In this white paper, you’ll learn:
- Why to account for the impact of temperature drifts on the frequency response before beginning the design process
- How the PIM measurement setup and specifications can affect the product
- The ways to prioritize varying requirements
One of the key enabling technologies in the development of autonomous vehicles is driving aid radar systems. This paper focuses on some of the challenges experienced during the design and integration of automotive radars. The applicable numerical solutions that FEKO offers is also discussed. Radar channelling modelling from WinProp, one of Altair’s latest acquisitions in the EM space, will also be presented.
Capturing unpredictable EW transmissions could mean hours or even days of continuous recording of the RF signal environment. See selected videos and application content designed to help you simplify the recording and analysis of these hard-to-catch RF transmissions.
Review the basics of spectrum analysis including the various signal analyzer architectures from single stage to superheterodyne. Also discover how to adjust VSA settings for optimal measurement performance.
In the 22 years since it was opened for satellite communications, Ku Band has become an essential part of the radio spectrum. Today, there are systems in place that provide video and data distribution for internet access, television news gathering, home radio and television programming, in-flight Wi-Fi and cellphone networks, plus high capacity data networks for commercial and government applications.
This application note compares the commonly-implemented power measurement test setups for TVAC with a new test method that uses TVAC-qualified LAN power sensors. The paper explains how this new test method provides a simplified test setup, and more accurate and reliable microwave power measurements for TVAC testing of satellite equipment.
Electromagnetic Compatibility (EMC) has become a key and sensitive topic for OEM’s and suppliers in many industries. Not only is it important to ensure electromagnetic problems will not occur when integrating components and devices in a system, but also to fulfil the related EMC regulations. FEKO is used for EMC to simulate problems related to Electromagnetic Interferences (EMI) and Electromagnetic Susceptibility or Immunity (EMS).
