Detectores con Diodos Zero Bias (ZBD) para banda W

Abstract

Increasing demand for applications in W band has pushed the development of technologies for generation, mixing and detection of RF signals in these bands. Particularly, high performance diodes specially developed to operate at zero bias are well suited for detection. Modeling of Zero Biased Diodes (ZBD) manufactured by Virginia Diodes is presented and then applied to the design of a detector. Different configurations have been used to mount the diodes (flip-chip, and wire-bonded) requiring a careful de-embedding. Several versions of the detector have been implemented, measured, and compared with simulations done with the previously obtained diode model, showing the most critical points of the detector development.
