Abstract:
1. A device for use with a transmission signal generator, a duplexer and an antenna, the transmission signal generator being operable to generate a transmission signal, the duplexer being operable to provide a transmit signal to the antenna, the antenna being operable to transmit the transmit signal, to receive a reception signal and to provide the reception signal to the duplexer, the duplexer being further operable to separate the transmit signal from the reception signal and to generate a duplexed signal, said device comprising: a first transmitter operable to generate an output signal based on the transmission signal; a second transmitter operable to generate a modifying signal; and a receiver having a second order intercept point and being operable to receive a third signal, said receiver comprising an I channel, a Q channel and a processing portion, said processing portion being operable to calibrate the second order intercept point and to compensate for I/Q imbalance between said I channel and said Q channel, wherein the third signal is based on the modifying signal.
