高效无源三次倍频器研究与设计

为解决目前市面上毫米波倍频器制作工艺与体积之间的矛盾,设计了一款工艺简单、体积小、效率高、成本低的毫米波无源三倍频器。该倍频器在印制电路板上采用砷化镓变容二极管的反向并联电路结构,能有效抑制偶次谐波,改善输入阻抗特性;并在电路中增加空闲电路,大大提高了倍频信号的输出功率;最后通过仿真软件对倍频器进行优化和仿真,结果表明该倍频器效率高达55.78%、基波抑制大于50 dBc。

Research and Design of Efficient Passive Frequency Tripler

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.
