The present disclosure relates to a method for demodulating a radio frequency (RF) signal comprising the steps of determining the nearest harmonic of a clock signal from a central frequency (Frx) of a received frequency band; and, if said nearest harmonic is in said frequency band, setting an intermediate frequency (IF) of a Near Zero Intermediate Frequency (NZIF) receiver to the difference (SpurOffset) between said central frequency (Frx) and said nearest harmonic.

Method for demodulating a RF signal in the presence of inband harmonic spurs

The present description concerns a communication device including a first communication circuit coupled to a first antenna port of the communication device; a switch having first, second and third terminals, the first terminal being coupled to a second antenna port of the communication device, the switch being configured to switch between a first state in which the first terminal is coupled t the second terminal and a second state in which the first terminal is coupled to the third terminal; a third port coupled to the second terminal of the switch; and a second communication circuit coupled to the third terminal.
