Abstract
Methods and apparatus, including computer program products, are provided filters. In some example embodiments, there is provided a radio frequency filter including at least one resonant circuit selectable to vary at least the selectivity of the radio frequency filter, wherein the selectivity is varied based on at least one of a first amount of transmit power being used at a user equipment and a second amount of received signal power. Related apparatus, systems, methods, and articles are also described.
Claims19
An apparatus comprising:
- a transmit radio frequency filter comprising a plurality of first resonant circuit filter stages, each of the plurality of first resonant circuit filter stages configured to be switched in or out of the transmit radio frequency filter to vary at least a selectivity of the transmit radio frequency filter;
- and
- a receive radio frequency filter comprising a plurality of second resonant circuit filter stages, each of the plurality of second resonant circuit filter stages configured to be switched in or out of the receive radio frequency filter to vary at least a selectivity of the receive radio frequency filter;
- wherein the selectivity of the transmit radio frequency filter and the selectivity of the receive radio frequency filter is varied based on at least one of a first amount of transmit power being used at a user equipment and a second amount of received signal power.

A method comprising:
- varying at least a selectivity of a transmit radio frequency filter comprising a plurality of first resonant circuit filter stages, each of the plurality of first resonant circuit filter stages configured to be switched in or out of the transmit radio frequency filter, by at least switching in or out each of the plurality of first resonant circuit filter stages;
- varying at least a selectivity of a receive radio frequency filter comprising a plurality of second resonant circuit filter stages, each of the plurality of second resonant circuit filter stages configured to be switched in or out of the receive radio frequency filter, by at least switching in or out each of the plurality of second resonant circuit filter stages;
- wherein a selectivity of the transmit radio frequency filter and a selectivity of the receive radio frequency filter is varied based on at least one of a first amount of transmit power being used at a user equipment and a second amount of received signal power.
