DATA SHEET Silicon Schottky Barrier Diodes in Hermetic and Epoxy Ceramic Packages Applications  Detectors  Mixers Features  Available in both P-type and N-type low barrier designs  Low 1/f noise  Packages rated MSL1, 260 C per JEDEC J-STD-020 Description Our packaged Schottky barrier detector diodes are designed for applications through 20 GHz in the Ka band. They are made by the deposition of a suitable barrier metal on an epitaxial silicon substrate to form the junction. The process and choice of materials result in low series resistance along with a narrow spread of capacitance values for close impedance control. P-type silicon is used to obtain superior 1/f noise characteristics. N-type silicon is also available. Packaged diodes are suitable for use in waveguide, coaxial, and stripline applications. The choice of N- and P-type silicon allows the designer to optimize the silicon material for the intended application:  Doppler mixers and high-sensitivity detect...
