A microwave mixer suitable for millimeter wave radar applications. A semi-insulating gallium arsenide dielectric waveguide structure contains an embedded planar doped barrier PDB structure as a non-linear mixing element. The local oscillator LO signal is guided to the PDB structure via a coplanar type waveguide. The radio frequency RF signal is guided to the PDB structure via an image guide and a microstrip circuit serves to transmit the intermediate frequency IF.
