Abstract
A radio frequency front end system has a first transmit path and a first receive path. There is a first transmit filter within the first transmit path and a first receive filter within the first receive path. One or more switches can be configured to selectively connect a first antenna to the first transmit filter and to selectively connect a second antenna to the first receive filter to allow frequency division duplex communication over the first transmit path and the first receive path in which the first transmit path transmits over the first antenna simultaneous with the first receive path receiving over the second antenna.
Claims20
A radio frequency front end system comprising:
- a first transmit path and a first receive path;
- a first transmit filter within the first transmit path and a first receive filter within the first receive path;
- and
- one or more switches configured to selectively connect a first antenna to the first transmit filter and to selectively connect a second antenna to the first receive filter to allow frequency division duplex communication over the first transmit path and the first receive path in which the first transmit path transmits over the first antenna simultaneous with the first receive path receiving over the second antenna.
A mobile device comprising:
- a first antenna and a second antenna;
- and
- a front end system including a first transmit path and a first receive path, a first transmit filter within the first transmit path and a first receive filter within the first receive path, and one or more switches configured to selectively connect the first antenna to the first transmit filter and to selectively connect the second antenna to the first receive filter to allow frequency division duplex communication over the first transmit path and the first receive path in which the first transmit path transmits over the first antenna simultaneous with the first receive path receiving over the second antenna.
A method of operating a radio frequency system comprising:
- actuating one or more switches to selectively connect a first antenna to a first transmit filter, the first transmit filter within a first transmit path;
- actuating the one or more switches to selectively connect a second antenna to a first receive filter, the first receive filter within a first receive path;
- and
- operating the first transmit path and the first receive path to perform frequency division duplex communication over the first transmit path and the first receive path in which the first transmit path transmits over the first antenna simultaneous with the first receive path receiving over the second antenna.
