ABSTRACT:
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).
