Phase-Locked Loop Frequency Synthesizer

Frequency synthesizers are vital components used in various electronic systems, such as communication and radar systems, to generate a variety of frequencies from a single reference. These synthesizers are required to have a wide tuning range and a small tuning step while maintaining low phase noise and reference spurs. Current frequency synthesizers often consume a great deal of power and are disproportionately large, making them unwieldy and inefficient for certain uses. These limitations pose a problem to progressive advancements in electronic systems application.

Technology Description

This frequency synthesizer offers an exceptional wide output frequency range and tiny tuning steps. Its design ensures that in-band spurious components are kept minimal, while simultaneously reducing phase noise. This innovative frequency synthesizer has the added advantage of being fabricated as an integrated circuit device. This compactness, paired with low power dissipation, makes it highly useful. The uniqueness of this device lies in its application in wideband frequency systems. It can effectively replace multiple frequency synthesizers, each dedicated to a fraction of the entire system’s frequency range. This capability can dramatically decrease both the cost and footprint of these systems while increasing overall performance by providing a diverse frequency range with precise tuning control.
