Critical guidelines for RF and microwave PCB Design
A few decades ago, there wasn’t much demand for RF and microwave circuits. They were difficult to design into the architectures of the time, and so costly that only mil/aero projects could afford them. But today RF circuitry is crammed into a large variety of commercial products. Most of these are handheld wireless devices for medical, industrial, and communications applications, plus applications in a variety of fields are migrating from desktop models to become portable communications units. Not only is RF becoming more ubiquitous, but microwave circuitry as well, both capturing very high frequencies (VHF) and ultra-high frequencies (UHF).
