Abstract
The present invention provides an integrated circuit for communication, e.g., for mobile radio-frequency (RF) telecommunication, including a resonator, a main amplifier, a matching circuit, a blocker detector, a mixer circuit, and a translation filter. The resonator provides conversion from single-end to differential, and filtering function for rejecting blockers at harmonics of local oscillation signal. The blocker detector detects occurrence of blocker; according to whether blocker exists, the main amplifier amplifies differential signal of the resonator by different gains, and the mixer circuit mixes amplified signal with different numbers of mixers. The translation filter contributes to rejection of blockers closed to in-band by providing a first pass band which is translated to a second pass band by the mixer circuit. The matching circuit provides impedance match.
