Abstract
A communication apparatus includes transmission circuitry and a frequency conversion unit. The transmission circuitry is configured to down-convert an input Intermediate Frequency (IF) signal using a transmit (TX) Local Oscillator (LO) signal so as to produce a TX baseband signal, to up-convert the TX baseband signal to produce an output Radio Frequency (RF) signal, and to send the output RF signal to an antenna. The frequency correction unit is configured to estimate a frequency of the TX baseband signal or of the input IF signal, and to adjust the TX LO signal based on the estimated frequency so as to cause the transmission circuitry to down-convert the input IF signal to a predefined target frequency.
