Abstract: This invention includes a circuit design that can be used for the purpose of altering the frequency response either as a standalone circuit or in combination with that of an existing filter. This asset behaviour is combined with existing circuits of RF front-end designs using 5G NR n79 and Wi-Fi 802.11 a/n/ac as exemplary co-existing systems that would benefit from the invention. The control of the circuit is included as an example for the co-existence of 5G NR n79 and Wi-Fi 802.11 a/n/ac, in which the most beneficial utilization of the added assets of the circuit are realized by using a control method that prioritizes own radio needs as highest priority, but at the same time allow the co-existing radio technology to get support when there’s sufficient signal quality to relax performance of own link. Fig. 1 depicts the invention.
