This fast-switching frequency synthesizer keeps the spurious and phase-noise levels low across a total frequency tuning range as wide as 50 MHz to 21 GHz. Microwave signal sources must deliver on many different levels. Depending on the application, they may need to switch frequencies quickly, often in fine frequency steps, and always with low phase noise. Achieving this combination of high performance ...

Yttrium Iron Garnet (YIG) is a synthetic crystal that offers very high Q characteristics. (Learn more about Q factor in this wiki post: https://en.wikipedia.org/wiki/Q_factor ). This high Q provides the lowest phase noise performance in oscillators, and the most optimal multi-octave frequency tuning in both oscillators and filters. YIG crystals are “grown”, like silicon crystals. The ...

1. YIG RF Bandpass Filters: In an RF bandpass filter, the coupling loops are aligned at a 90° angle to prevent direct RF coupling. One end of each loop is grounded. This prevents the filtered signal from being reflected. The RF input signal of the coupling loop modulates the magnetic field around the YIG sphere, this modulation is coupled to the magnetic field resonating around the YIG sphere, ...

Using small conductive “loops” a YIG filter is coupled to and from a YIG spheres’ resonant magnetic field. The closer the loop, the wider the bandwidth. Bandwidth can also be expanded by increasing the number of YIG resonators and carefully “tuning” the RF coupling loops. In this brief, RF engineers will learn the three basic methods in which this coupling is applied: ...
