Claim:
1. A wireless receiver, comprising: an out-band signal bypass filter, having a first terminal and a second terminal respectively receiving a positive differential signal and a negative differential signal from a former-stage circuit, wherein the out-band signal bypass filter provides an out-band signal bypass path from the first terminal to the second terminal; a mixer, receiving a filtered signal from the out-band signal bypass filter; and a baseband circuit, coupled to the mixer for generation of an in-phase signal and a quadrature phase signal, wherein: the out-band signal bypass filter further comprises a third terminal, a fourth terminal, a fifth terminal and a sixth terminal coupled to the mixer; and the out-band signal bypass path includes a first branch from the first terminal to the third terminal to the mixer and back to the out-band signal bypass filter via the fourth terminal and from the fourth terminal to the second terminal, and a second branch from the first terminal to the fifth terminal to the mixer and back to the out-band signal bypass filter via the sixth terminal and from the sixth terminal to the second terminal.
