Radio-Frequency Devices

Variable Capacitance Diodes 更多

These diodes have the capacities variable depending on the value of the reverse bias voltage applied between the anode and the cathode. They are also called VCDs (Variable Capacitance Diodes) or VariCaps. They are used in radio-frequency matching circuits for electronic tuning.

Radio-Frequency Switching Diodes 更多

They are particularly optimum for switching UHF/VHF frequency band of TV tuners.

Radio-Frequency Schottky Barrier Diodes 更多

Making use of rectifying property brought about by contact of a metal and a semiconductor, in place of P-N junction, these diodes are activated by a majority carrier. They are suitable for radio-frequency signal mixer circuits because the forward voltage is low and the reverse recovery time is short.

高频器件

可变电容二极管 更多

这些二极管的电容将根据阳极和阴极之间所施加的反向偏置电压值变化而变化。它们也称为VCD(可变电容二极管)或VariCaps。它们应用于电子调谐的射频匹配电路。

射频开关二极管 更多

它们特别适用于切换TV调谐器的UHF/VHF频带。

射频肖特基二极管 更多

这些二极管利用通过金属和半导体接触而非P-N结点得以实现的整流特性,可由大多数载体进行激活。它们因为正向电压低以及反向恢复时间短而适用于射频信号混频器电路。
