Abstract: Techniques for providing a jammer-resistant noise-cancelling receiver front end with band-pass impedance matching and good power efficiency. In an aspect, the center frequency of the band-pass impedance matching advantageously tracks the local oscillator frequency. In an aspect, first and second receive signal paths are provided, with an R-C network coupled to the output of the second receive signal path. The resistance of the R-C network may be selected to provide band-pass impedance matching to the RF input signal.

Abstract: The transmission path of a communication device includes, in part, N upconverters each of which receives M phases of a signal to be transmitted. Each upconverter further receives one of N sets of phases of a LO signal. Each of the N sets includes M phases of the LO signal. The communication device further includes at least one combiner, and N amplifiers each responsive to a different one of the N upconverters to generate N amplified signals. The combiner combines the N amplified signals to generate an output signal. By selecting the gain of one of the amplifiers to be different than the gain of the remaining amplifiers, the undesired harmonics of the signal to be transmitted, caused by non-linearity of the amplifiers, is reduced. Each upconverter optionally includes a multitude of upconverters whose outputs are combined to further reduce the spurious harmonic upconversion products and the counter-intermodulation distortion (IM3).
