Abstract
Provided is a transceiver. The transceiver includes: a transmission unit modulating at least one of a plurality of baseband transmit signals to an RF band and amplifying the modulated at least one; a duplexer transmitting transmit signals outputted from the transmission unit to an antenna by selecting a signal in a downlink frequency band or an uplink frequency band or filtering a receive signal received from the antenna by the downlink frequency band or the uplink frequency band; a reception unit demodulating the receive signals in the downlink frequency band or the uplink frequency band from the duplexer into at least one baseband signal; a first switch delivering a transmit signal provided from the transmission unit to a first RF band filter of the duplexer in a first communication mode and a second communication mode; and a second switch delivering a first receive signal delivered from a second RF band filter of the duplexer to the reception unit in the first communication mode and a third communication mode, wherein each of the transmission unit and the reception unit includes one power amplifier and one low noise amplifier.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
