Abstract : A broadband millimeter wave (26.5-40 GHz) mixer/-converter utilizing slotline and coplanar strip-line for the construction of the hybrid junction. The RF and local oscillator signals are applied 180 deg out of phase to a pair of beam-lead diodes. A diplexer consisting of a low-pass filter and a bandpass filter is also provided to separate the IF and LO signals. A first microwave integrated circuit (MIC) card carries the waveguide to slotline transition, the slotline transmission section, the tapered coplanar waveguide section and the LO bandpass filter. A pair of Schottky-barrier diodes are connected across the transmission channels of the coplanar waveguide section to form the hybrid junction. The LO input is applied to a section of suspended strip-line on this first MIC card. A second MIC card carries the IF low-pass filter and couples to the IF output of the mixer. (Author)
