Abstract
Abstract—Nonlinearity and time-variance in Radio Frequency
(RF) circuits leads to unwanted harmonics and intermodulation
products, e.g. in power amplifiers and mixers. This paper
reviews a recently proposed multipath polyphase circuit
technique which can cancel such harmonics and
intermodulation products. This will be illustrated using a power
upconverter IC as an example. The upconverter works from DC
to 2.4 GHz, and the multipath polyphase technique cleans its
spectrum up to the 17th harmonic, keeping unwanted spurious
responses more than 40dB below the carrier. The technique can
also be useful for other applications, and some possible
applications will be discussed.
