This paper introduces an approach to increase the maximal sample frequency of lattice wave digital filters based on circulators and Richards- structures. In this approach the allpass branches of the filters make use of cascaded first-order and constrained third-order Richards- allpass sections. Compared with the case in which regular first- and second-order Richards- allpass sections are used, the maximal sample frequency is here two times higher. This is generally paid for by a somewhat higher computational complexity.
