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.

Modern modular digitizers, like the Spectrum M4i series PCIe digitizers, offer greater bandwidth and higher resolution at any given bandwidth than ever before. Although they are in the class of general purpose measuring instruments they are capable of many RF and lower microwave frequency measurements. This article focuses on some examples of common RF measurements that can be performed with these modular digitizers.

Today's AWGs can address a broad range of applications and test cases. This primer discusses characteristics and fundamentals of arbitrary waveform generation and the different implementations available in the market. It also shows examples how to generate digital, multi-level and PAM4 signals, wireless and modulated waveforms, multi-carrier as well as coherent optical signals. It explains the different methods of wideband IQ modulation and up-conversion, calibration and correction, and wrap-around handling for RF/wireless signals.

Intermodulation distortion (IMD) is an important consideration in microwave and RF component design. A common technique for testing IMD is the use of two tones. Two-tone testing for IMD has been used to characterize the non-linearity of microwave and RF components, both active and passive, for a very long time. Traditionally, this has been done at fixed frequencies using multiple signal generators, a combiner, and a spectrum analyzer. Because IMD varies with frequency, these measurements must be repeated at various frequencies to get a clear picture of what a deviceâ??s true behavior is across its specified operating range. This can be a time consuming process using the traditional signal generators and spectrum analyzers. The Anritsu VectorStar MS4640B Series Vector Network Analyzers can be used to quickly and accurately make S parameter, gain compression, fixed and swept frequency IMD measurements using a single cable connection to the DUT.
