The present invention relates to an ASK modulator using an NRD gude. According to the present invention, by installing a diode mount which is equipped with the Schottky Barrier Diode on the end of the NRD gude, the modulation is made possible through the repeated variation of the reflected output depending on the degree of absorption against the incident oscillated wave coming through the NRD. In addition, the present invention makes it possible to accomplish the ASK modulation with the excellent absorption/reflection ratios because of the air gap inserted between the end of the NRD guide and the diode mount, which enhances the VSWR characteristic. |
