Designs include linear phase filters, a wideband phase shifter, and chirp filters with fractional bandwidths exceeding 100% .
chirp bandwidths that can be synthesized are 160 MHz, 40 MHz and 10 MHz.
They are available in three bandwidths, for dialup modem and broadband users.
stub matching is only desirable for relatively low fractional bandwidths.
