Abstract
A broadband non-resonant microwave frequency halver which simultaneously decouples the input frequency from the output port through phase cancellation and couples the subharmonic frequency to the output port through phase addition providing good isolation between input and output over a very broad frequency range. The implementation of this circuit specifically excludes resonant, or frequency dependent elements and therefore has a much broader band of operation than previous circuits which relied on resonant phenomena.
