Jerry - sorry, but do you know what you are talking about?
A filter that is characterized by its lower cut-off is a high pas filter.
However, in your first posting you spoke about a bandpass.
Some basics:
A bandpass is described by (1) its center frequency (2) its bandwidth (lower und upper cut-off) and (3) by some attenuation requirements inside and outside the bandwidth. This results in a minimum order the transfer function must have.
More than that, if tuning is required, the tuning range is to be given and - a very critical requirement - if the bandwidth or the q-factor must be kept constant.
More than that, tuning requirements must be described in detail: passive R- or C- tuning ? Or electronic tuning (with control voltage) ?
Nobody can give you some hints if you don't deliver sufficient information. Sorry.
