| 1. A device comprising:
a receiver configured to connect to a first antenna, the receiver comprising first control logic configured to generate a
notification of the receiver being able to receive a reception frequency band,
a transmitter configured to connect to at least one second antenna and to the receiver, the transmitter communicating radio
frequency signals in a selected one of at least one transmission frequency bands over a radio frequency transmit path to the
at least one second antenna, the transmitter comprising:
second control logic;
at least one filter; and
at least one switch coupled to the radio frequency transmit path, the at least one filter, and the second control logic, the
at least one switch configured to modify the radio frequency transmit path to couple a given one of the at least one filters
or to decouple the given filter from the radio frequency transmit path,
wherein the second control logic is responsive to the notification to cause the at least one switch to modify the radio frequency
transmit path to couple the given filter to the radio frequency transmit path,
where the modified radio frequency transmit path is selected to reduce interference between the transmission frequency band
using the modified radio frequency transmit path and the reception frequency band.
