Resumen
This paper is focused on the theoretical investigation
of the relationship between the time average stored energy (t.a.s.e)
in conventional lumped-element Chebychev low-pass prototype
filters, and the sensitivity of the return loss with respect to
properly tuned resonators. It is well known that the resonant
frequencies are the most sensitive parameters in a filter to
achieve the required return loss and often some form of manual
adjustment is needed. Different degree transfer functions, and
also different topologies, are investigated throughout the paper.
It is shown that both, the t.a.s.e and the sensitivity behaviors
are strongly related. This work provides some new insight in
fundamental properties of passive filters and can be useful for
the design of filters with reduced sensitivity for high power
applications and tuningless filters, for example.
