Articles on Test and Measurement

This Article by Sonoko Akamatsu, Charles Baylis, and Larry Dunleavy details the design goals and simulation- based processes for Power Amplifier Design.

This Article by Dean Nicholson presents a design methodology proposed for designing and building RF circuits likely to contain discontinuous regions.

This Article describes the process for developing and implementing an effective power amplifier linearization scheme using baseband adaptive digital pre-distortion.

To better understand CCDF curves, a digitally modulated signal is examined. Unfortunately, the signal in this form is difficult to quantify because of its inherent randomness and inconsistencies. In order to extract useful information from this noise-like signal, a statistical description of the power levels in this signal is used.

Having high-frequency design tools resident on a Vector Network Analyzer (VNA) provides a streamlined work flow that eliminates the time required to transfer measured data to a simulator running on a separate PC or workstation. This is one of the unique advantages provided by AWR Connected for Anritsu VectorStar, in which AWR's Microwave Office so...

This Whitepaper goes over the design of a 110 dB, 10 MHz to 8 GHz, Electronic Step Attenuator for Fast Switching Microwave Signal Generators.

An ideal signal has no phase noise, harmonics nor spurious frequency components associated with it. Unfortunately the ideal signal does not exist in the real world, and these factors degrade the spectral purity of all real world signals to some degree. High-performance microwave signal generators are designed to maximize spectral purity, with very low l...
