Abstract :
A balanced resistive mixer topology is proposed, that avoids the requirement of an external 180/spl deg/ IF hybrid. Instead of a balun, the IF signal is extracted once at the drain and once at the source of the balanced FETs. Thus, the IF signals can simply be combined. Operating as up- and downconverter, the fabricated MMIC mixer has a measured conversion loss of better than 10 dB over a frequency range from 29 to 39 GHz.
