ELLIPTIC_HIGH_PASS_LOW_PASS

Published:2009/7/3 3:38:00 Author:May | From:SeekIC

Covers 1.45 to 32 MHz in six steps, for use at front end of high-frequency communication receiver to suppress unwanted broadcast signals. Low-pass filter section, acting with one of six following low-pass sections, gives over 90-dB image suppression. Special Bessel-Cauer elliptic filter having Chebyshev response in passband provides required 50-ohm impedance matching so filters can be cascaded.-U. L. Rohde, Optimum Design for High-Frequency Communications Recoivers, Ham Fladio, Oct. 1976, p 10-25.
