  Abstract

In this paper, a Ka-band harmonic mixer is designed and fabricated on the base of the multiplier theory that there is a bias point to maximize the third harmonic order(3f_(LO)) with respect to a fundamental LO frequency(f_(LO)), which can make the high-order mixing element(f_(RF)± 3f_(LO)) to be greater than other mixing elements, pumping a RF frequency(f_(RF)) and LO frequency(f_(LO)).
The harmonic mixer by the proposed design method is fabricated by using a commercial GaAs MESFET device with a plastic package and overcome these disadvantages that a conventional mixer in Ka-band suffer from a high cost, inefficient productivity and circuit complexity. The harmonic mixer have a -10 ㏈ conversion loss at the IF frequency(3f_(LO)-f_(RF)=1.0㎓) by selecting a gate bias voltage for the maximum third-order LO harmonic element(3f_(LO)=34.5 ㎓) as pumping LO frequency(f_(LO)=11.5 ㎓) with respect to RF frequency (f_(RF)=33.5㎓).
