Crystal filter bandwidth
WebThe crystal band pass filters are available in frequencies up to 250 MHz, in connectorized, surface mount, PC board mount, and drop-in type packages, with a length ranging from approximately 1 to 5 in. The Crystal bandpass filter is just one of the many products that Anatech Electronice offers to RF design engineers looking for quality filters ... WebThe crystal has a series-resonant frequency based on just C_ser and L. It has a relatively low impedance (basically just R) at this frequency. It also has a parallel-resonant frequency when you consider the entire loop, including C_par.
