Power amplifier (PA) performance under small- and large-signal operating conditions is contingent upon the output impedance match (load). As a result, PA designers must determine the ideal output load for system-driven amplifier requirements such as output power at a given saturated power (compression point), efficiency, and/or linearity.
New active electronically-scanned arrays (AESAs) are being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed in new and novel ways, size and performance requirements are becoming critical and are being addressed through innovative architectures and system capabilities. This white paper examines these technology trends and presents several examples where advances in NI AWR Design Environment are supporting next-generation AESA and phased-array radar development.
The latest release of NI AWR Design Environment, V13, will be on display at the Electronic Design Innovation Conference (EDI CON) 2017, being held
in Shanghai, China on April 25-27. In addition to software demonstrations within NI Booth #311, the NI AWR software product portfolio will be featured in one 40-minute workshop and two 20-minute technical sessions. NI AWR software activities during EDI CON include:
WIPL-D d.o.o., a Serbian developer of commercial electromagnetic (EM) software, has become a key alliance partner and original equipment manufacturer (OEM) supplying its technology for use within NI AWR software, specifically AntSyn™ antenna synthesis and optimization module.
Mitsubishi Electric Corp. has developed a new methodology to improve testing for electromagnetic compatibility (EMC) of its DIATONE automotive navigation/audio systems using NI AWR Design Environment, specifically Microwave Office circuit design software and AXIEM 3D electromagnetic (EM) simulation.
NI, the provider of platform-based systems that enable engineers and scientists to solve the world's greatest engineering challenges, announced that its Board of Directors has elected Alex Davern, age 49, to serve as Chief Executive Officer and President of National Instruments, effective January 1, 2017.
NI announced the NI PXIe-4135 source measure unit (SMU) with a measurement sensitivity of 10 fA and voltage output up to 200 V. Engineers can use the NI PXIe-4135 SMU to measure low-current signals and take advantage of the high channel density, fast test throughput and flexibility of NI PXI SMUs for applications such as wafer-level parametric test, materials research and characterization of low-current sensors and ICs.
Ural Federal University students have successfully realized an RF miniaturized branch-line coupler using the NI AWR Design Environment™ platform, inclusive of Microwave Office circuit and AXIEM 3D planar electromagnetic (EM) simulators.
A new and improved EM Socket II architecture within NI AWR Design Environment™ has been developed in order to enhance the AWR Connected™ for EM interoperability between third-party electromagnetic (EM) simulation tools and the company’s flagship high-frequency circuit design software, Microwave Office.
