Abstract
Introduced here are approaches to mitigating the desensitization and intermodulation effects that can affect telecommunication performance of multiband electronic devices. Specifically, the present disclosure outlines an approach to mitigating the coexistence effect at the system level using tunable filters that are implemented or controlled via software.
Claims12
An electronic device comprising:
- a first tunable notch filter that is configured to filter radio signals propagating between a first antenna and a first transceiver associated with a first wireless standard;
- a second tunable notch filter that is configured to filter radio signals propagating between a second antenna and a second transceiver associated with a second wireless standard;
- a first diplexer configured to split filtered radio signals received from the first tunable notch filter into a first pair of radio signals;
- a second diplexer configured to split filtered radio signals received from the second tunable notch filter into a second pair of radio signals, and
- a modem to which the filtered radio signals are forwarded by the first and second tunable notch filters.

An electronic device comprising:
- a first tunable notch filter that is configured to filter radio signals propagating between a first antenna and a first transceiver associated with a first wireless standard;
- a second tunable notch filter that is configured to filter radio signals propagating between a second antenna and a second transceiver associated with a second wireless standard;
- and
- a modem to which the filtered radio signals are forwarded by the first and second tunable notch filters,
- wherein the modem is connected to the first tunable notch filter via a first control line, along which the modem is able to transmit a signal to tune the first tunable notch filter, and
- wherein the modem is connected to the second tunable notch filter via a second control line, along which the modem is able to transmit a signal to tune the second tunable notch filter.
