Patent ID: 7506016

Claim:
A multiplier device comprising: first to n th multipliers M 1 to M n that are configured to multiply a carrier modulated information signal with first to n th mutually phase shifted and identical, substantially square wave mixing signals MS 1 to MS n with 50% duty cycle, wherein n is greater than 2, first to n th weighting circuits with respective fixed weighting factors WF 1 to WF n that are configured to receive corresponding outputs of the multipliers M 1 to M n , and to produce therefrom corresponding weighted outputs an adder circuit that is configured to provide a sum of the weighted outputs, wherein: the mixing signals MS 1 to MS n have respective phase angles φ i corresponding to φ i =i*Δφ, and the weighting factors WF i correspond to sine values of said respective phase angles φ i =i*Δφ, with Δφ being the mutual phase difference between each two phase consecutive mixing signals corresponding to π/(n+1) and i varying from 1 to n.
