专利汇可以提供High burnout resistance schottky barrier diode专利检索,专利查询,专利分析的服务。并且A semiconductor rectifier device particularly suited for mixing and/or detecting electric wave signals in the microwave frequency range and having a high resistance to RF burnout is disclosed. A semiconductive region having an impurity concentration greater than a prescribed amount is located in a semiconductor body of opposite polarity to the region. A metal in face to face contact with the region and the semiconductor body forms an N-type and a P-type Schottky-barrier junction. A PN junction is also defined at the interface of the semiconductive region and semiconductor body such that under the influence of a low signal level no injection occurs at the PN junction but under the influence of a high signal level large injection occurs at the PN junction causing a large change in the impedance and capacitance of the device. As a result the semiconductor device, previously matched to the line at low RF signal level becomes mismatched and highly reflective of RF energy at high RF signal level, thus preventing burnout. (For the purposes of this disclosure low signal level is defined as 1-2 mW. typically of electromagnetic energy but no greater than 50 mW. per diode, whereas high signal level is any electromagnetic energy over 50 mW.,下面是High burnout resistance schottky barrier diode专利的具体信息内容。
