Crystal phasing filter
WebJan 30, 2024 · Liquid Crystals. A true liquid is isotropic, meaning that its properties are uniform in all directions— the result of its molecules being in constant random motion. Crystalline solids, in contrast, are anisotropic; optical- and other properties such as thermal and electrical conductivity vary with direction. A liquid crystal phase has many of ...

The phasing control is acting like a variable notch filter. I may also have a weak crystal because the filter should be much more narrow banded in the 4 and 5 position.

The filter has individual sections with discrete crystal devices. In one embodiment as a 55 MHz trap, the filter has a passband from about 50 MHz to about 212 MHz with a 1 KHz stop band about a center frequency that may be tuned by means of a laser-trimmed bridging resistor.
