L. Billonnet et al., NEW DESIGN TECHNIQUES FOR HIGH-ORDER NARROW-BAND MICROWAVE FILTERS DERIVED FROM LOW-FREQUENCY RECURSIVE CONCEPTS, Microwave and optical technology letters, 6(14), 1993, pp. 809-813
We show how high-order narrow-band microwave filters can be built with
the help of various unitary first-order recursive cells in strict acc
ordance to low-frequency principles. We illustrate our approach with t
he simulated results for a third-order filter in the 2.25-8.4-GHz freq
uency range. (C) 1993 John Wiley & Sons, Inc.
