(a) and (b) show the high-frequency signal input switching circuit . Diodes are used in the signal transmission channel . When the diode
is on, the signal passes through, and when the diode is off, the signal is blocked. It can be used for two input signals and A selector switch control circuit with an output signal,
using high frequency diodes for switching. The DC voltage controls the diode
in the signal transmission circuit. When forward bias is applied, it is turned on, and when there is no forward bias, it is turned off. It is suitable for
signal control switching in TV, video recorder and cable TV systems. The signal frequency can reach 10-500 MHz.
