With many groups now beginning to consider the drivers for 5th Generation wireless networks, this timely document includes contributions from 20 IWPC member organizations from around the world and aims to advance certain understandings and concepts for adoption in wireless systems to be deployed beyond the year 2020. This 89 page document covers a broad range of 5G topics with emphasis on mm-wave.
Read this application note for an overview of the key challenges in testing power amplifiers and front end modules with envelope tracking. Learn about how to reduce test cost, achieve fast throughput, and maintain high test quality using the modular Keysight M9381A PXIe VSG, and the M9391A or M9393A PXIe VSA, as well as how to perform high speed harmonic test using the M9393A PXIe VSA.
The theories and operations of intermodulation distortion (IMD) are well understood. It is one of the key metrics in categorizing the linearity of active and passive electronic components and devices. There are various instruments available from leading equipment manufacturers to perform IMD measurement in the RF and microwave region - two signal generators, a power combiner and a spectrum analyzer; a vector network analyzer with a signal generator and a power combiner. However, extending the IMD measurement to the millimeter wave and sub-millimeter wave frequency ranges is quite another matter.
A newly developed superconducting RF MEMS varactor provides additional capabilities for digital transmission, including tunable filters for improved signal selectivity and noise rejection. Development of the superconducting circuitry at cryogenic temperatures takes advantage of advanced probe station technology from Lake Shore.
Low noise amplifiers (LNAs) play a key role in radio receiver performance. The success of a receiver's design is measured in multiple dimensions: receiver sensitivity, selectivity, and proclivity to reception errors. The RF design engineer works to optimize receiver front-end performance with a special focus on the first active device. This paper considers device- and board-level variables that affect LNA performance and confront the engineer at each level of design in accommodating the various requirements of specific applications.
In this paper, we present a versatile and robust fabrication method to build circuit boards used for RF and microwave telecommunication devices over a large frequency of interest from MHz up to several tens of GHz range.
Do you have confidence that your 50 MHz reference port Standing Wave Ratio (SWR) is within specifications? It is important to have this confidence and by adhering to these procedures, you can be certain that your 50 MHz reference is within the manufactures tolerance!
This White Paper provides a view on radar waveforms for Aerospace and Defence and commercial radar systems. Waveforms such as pulse and pulse-Doppler signal, continuous wave and frequency shift keying waveforms are described. It also shows continuous waveform trends designed for specific needs and application differences of continuous wave radar compared to pulse radar systems.
This application note introduces the practical aspects of cable and antenna testing. It covers interpreting measurement results and instrument operation including calibration options such as CalReady and QuickCal using FieldFox configured as a cable and antenna analyzer. Measurement examples are provided showing techniques for measuring insertion loss, return loss, and locating faults in a transmission system.
