Planar Doped Barrier Devices for Subharmonic Mixers

Authors:
J.R. East, T. Lee, G.I. Haddad
Abstract:
Mixers are a critical component of most millimeter wave and THz systems. Often, the front end mixer performance determines the overall system performance. At higher millimeter wave and THz frequencies, mixer performance can be limited by the lack of low cost solid state sources. A subharmonic mixer with a pumping frequency at half the signal frequency would reduce the source power requirements at these higher frequencies. Typical subharmonic mixers use back to back Schottky barrier diodes. The resulting structures are difficult to fabricate, and the performance can be degraded if the diodes are not matched and by parasitics associated with the various connections. One possible solution is to use an integrated Schottky barrier structure. Another possible solution is to use a planar doped barrier (PDB) as a single device subharmonic mixer. This paper will present an analysis of PDB subharmonic mixer performance.
