Abstract
Described are broadband active coupling circuits and methods. A broadband active coupling circuit includes a high-pass circuit configured to provide a high frequency response for a broadband signal and a low-pass circuit connected in parallel with the high-pass circuit. The low-pass circuit is configured to provide a low frequency response for the broadband signal, where the low-pass circuit includes an active circuit configured to minimally impact the high frequency response provided by the high-pass circuit.
