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).
This NI AWR Design Environment(TM) white paper, "Design of Class F Power Amplifiers Using Cree GaN HEMTs and Microwave Office Software to Optimize Gain, Efficiency and Stability" details how Microwave Office circuit design software can be used to design power amplifiers employing Cree gallium nitride (GaN) high electron mobility transistors (HEMTs) to maximize power-added efficiency (PAE) by optimizing source and load pull at both fundamental and harmonic frequencies. The load-pull scripts that are available in Microwave Office circuit design software have been used extensively to find the optimum trade-offs in power gain, efficiency, and stability.
Solid State Power Amplifiers (SSPAs) incorporating GaN transistors provide compact and efficient sources of microwave power. CPI has developed a 1.5 kW X-band SSPA, CPI model VSX3622, for radar applications. The VSX3622 SSPA combines the power from two VSX3614 SSPAs, which each operate at nominally 1 kW, saturated. This paper will present details of the design and performance data for both amplifiers.
This NI AWR Design Environment(TM) white paper describes co-simulation capabilities of Visual System Simulator(TM) (VSS) system design software and LabVIEW, enabling system designers to better analyze, optimize, and verify complex RF systems inclusive of digital signal processing (DSP) blocks.
We will first present an overview of phased-array antenna fundamentals and basic Active Electronically Scanned Array (AESA) principles and challenges, and then we will explain how planar solutions can help with form-factor issues. We will also show how planar solutions at frequencies at or above X-band require increased integration, as well as highlighting some associated challenges.
High-performance inertial systems provide accurate platform heading information in a variety of applications and operational environments. However, the magnetometers used are susceptible to measurement distortion in the presence of any magnetic material. This white paper documents product integration and on-board calibration procedures that mitigate distortion and optimize overall product performance.
A key factor in designing Wireless Power Transfer (WPT) devices is the performance of the power transfer efficiency between coupled coils and resonators. Consequently, the ability to characterize these components and measure power transfer efficiency in real-time is paramount. Download the new application note to learn the theory of WPT, measurement requirements for components in WPT systems and how to characterize key parameters.
