DATA SHEET DME, DMF, DMJ Series: Silicon Beam-Lead Schottky Mixer Diodes – Singles, Pairs, and Quads in Ceramic Hermetic Packages Applications  Microwave integrated circuits  Mixers  Detectors Features  Low 1/f noise  Low intermodulation distortion  Hermetically sealed packages  Statistical process control wafer fabrication  Packages rated MSL1, 260 C per JEDEC J-STD-020) Description The Isolink silicon Schottky barrier mixer diodes are designed for applications through 20 GHz. Schottky barrier mixer diodes 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 with a narrow spread of capacitance values for close impedance control. A variety of forward voltages are available ranging from low values for low, or starved, local oscillator drive levels to high values for high drive, low distortion mixer applications. These Schottky barrie...
