For noise-critical portable applications, such as GPS receivers, connectivity, and sensing, power supply designers always had to choose between longer battery run time (from higher efficiency) or higher signal chain performance (from the increased sensor sensitivity possible with a quieter power supply). For line-powered industrial or communications equipment applications, designers have been forced to dissipate significant amounts of power in LDOs to achieve the desired noise performance. Achieving both low noise and high efficiency was impossible.
This training series discusses the key requirements of local oscillator in microwave/RF and GHz clocks in radio applications. The topics covered establish the key relationships between the requirements of a signal source and their impact in a radio system. After this training, you will be armed with the ability to understand the system requirements of your customer and how they pertain to a signal source so you can engage with your customer in a very meaningful way.
