Since the main components of the crystal filter are crystals, and the quality factor of the crystal is particularly high, the crystal filter mainly has the following features:
Narrow bandwidth bandwidth for crystal filter bandwidth
Low insertion loss Ordinary crystal filter can reach 3~6db
Small rectangular coefficient The transition zone can be made very steep, with a rectangular factor of 2 or even as small as 1 point.
The temperature characteristics are the same as the temperature characteristics of the crystal
