| 1 | This thesis presents the design and manufacture of a V-band frequency quadrupler. | |
| 2 | The phase jitter of output signal of the PLL( phase locked loop) frequency doubler is analyzed. | |
| 3 | Voltage and current relationship is used to qualitatively analyze frequency doubler . | |
| 4 | This high order multiplier can provide high-quality millimeter-wave signal source. | |
| 5 | In this paper, the theory of Nonlinear Transmission-Line(NLTL)frequency multiplier was discussed and the complete model of it was given. |
