| In order to solve the contradiction between the manufacturing process and the volume of the millimeter wave frequency doubler on the market, a millimeter wave passive tripler was designed, which is small, with low price, high efficiency and simple craft. The frequency multiplier adopts the anti-parallel circuit structure of GaAs varactor diodes on the printed circuit board, which can effectively suppress even harmonics and improve the input impedance characteristics; Then the idle circuit is increased in the circuit, which greatly improves the power of the output signal; Finally, the frequency tripler is optimized and simulated by the simulation software. The results show that the frequency tripler has an efficiency of 55.78%, and the fundamental suppression is greater than 50 dBc. |
