Publication number: 20220124591
Type: Application
Filed: Sep 27, 2021
Publication Date: Apr 21, 2022
Applicant: NOKIA TECHNOLOGIES OY (Espoo)

Application Number: 17/448,966

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.

Figure 1: All exemplary Wi-Fi operation states. First state is pure “through”, so no impact of the resonator replicator. Second state is for TX operation and serves with the resonator at the band edge to attenuate the TX interference. Third state is RX operation with the resonator tuned towards the OOB blocker for improved RX.
