DESCRIPTION
Constant Delay Filters are essential in wireless systems
that are transmitting or receiving data at rapid rates in
limited bandwidth channels. Here sharp filtering along
with constant group delay must be present. To this end,
Aeroflex has developed a series of high performance
bandpass networks that meet these requirements.
These high performance IF Filters utilize a constant-
delay / sharp attenuation parametric non-minimum
phase function polynomial. The design is based upon
minimizing selected coefficients of the power series
expansion of the group delay response (linear and para-
bolic terms) to minimize pulse distortion of the applied
signal while providing sharp attenuation characteris-
tics.
