WebJul 7, 2024 · Let's define ω s as the series resonant angular frequency. We can then solve this equation for C s or L. (1) i ω s L = − 1 i ω s C s. (2) L = 1 C s ω s 2. (3) C s = 1 L ω s 2. The series resonance can be found by the VNA by looking for a frequency where reactance is zero and resistance is on the order of 10 ohms. WebRakon provides a wide range of highly reliab le crystal filters for various s pace, defenc e and high-reliability applications.

WebGoing through a number of schematics for today's receivers (Elecraft KX3, for example) I note that most use LC circuits for filtering. The wikipedia article for Crystal Filters suggests, however, that crystal filters are used in high quality receivers:. A crystal filter is very often found in the intermediate frequency (IF) stages of high-quality radio receivers. WebWe measure exactly at the series resonance frequency, because there, XL and XCs sum up to zero. So what is left, is a (resistive) voltage divider, consisting of your source, the R from the quartz and the load. Whereas source and load are mostly 50 Ω. Please keep in mind to calibrate or to measure the difference (shorted / quartz inserted).
