GaN Solutions for Wide Bandwidths and High Frequencies

This eBook covers new market and design trends in GaN technology starting off with semiconductor trends in sub-6 GHz 5G Networks where the wider bandwidths and high efficiency are favoring GaN technology in many cases. Then Cobham covers AESA phased array and MIMO radar trends and new design techniques are covered with a modular system approach. The next two articles cover high efficiency GaN amplifier design techniques started with efficiency enhancement mechanisms for various class amplifiers and then a mmWave Doherty amplifier design. The last article introduces large-signal model technology by Wolfspeed and other resources available for high-frequency designers.

Oscilloscope Measurement Applications Guide

This eBook covers the design considerations for PCB laminate circuits and how to take these issues into account when designing for mmWave applications. Dielectric constant is a key material parameter that can vary due to temperature changes, within a substrate material due to the construction material, or over frequency. Dissipation factor is another key parameter that can affect the losses in a circuit and become very significant at mmWave frequencies. Metal surface roughness is another important consideration that can increase signal loss that is not significant at lower frequencies. The woven glass within the circuit material also causes changes in dielectric constant that can affect mmWave signals differently depending on the direction of the metal transmission lines. In addition, datasheets might not provide all of the information you need to simulate a circuit accurately.
