What is RF schottky diode ?

The figure-1 depicts schottky diode structure and its equivalent circuit. As shown it is formed by using metal semiconductor junctions at both the ends. Metals such as chromium, tungsten aluminium, platinum, gold etc. are used it its construction. It uses N-type silicon as semiconductor material.

The schottky diode is constructed on a thin silicon(n+ type) substrate by growing epitaxially on n-type active layer of about 2 micron thickness. Metal semiconductor junction is formed by depositing metal over SiO2.
