Multiplier device comprising first to n.sup.th multipliers M.sub.1 to M.sub.n for multiplying a carrier modulated information signal with first to n.sup.th mutually phase shifted and identical, substantially square wave mixing signals MS.sub.1 to MS.sub.n with 50% duty cycle. In order to eliminate fifth or higher order interferences from the output of said multiplier device according to the invention, n is greater than 2, outputs of said multipliers M.sub.1 to M.sub.n are respectively coupled through weighting circuits W.sub.1 to W.sub.n with respective fixed weighting factors WF.sub.1 to WF.sub.n to an adder circuit, said mixing signals MS.sub.1 to MS.sub.n having respective phase angles .phi..sub.i corresponding to .phi..sub.i=i*.DELTA..phi., said weighting factors WF.sub.i corresponding to the sine value of said respective phase angles .phi..sub.i=i*.DELTA..phi. with .DELTA..phi. being the mutual phase difference between each two phase consecutive mixing signals corresponding to .pi./(n+1) and i varying from 1 to n.
