在无线通信系统中,将通信频率提升到毫米波对于增加信道的容量,提高通信的抗干扰性具有很重要的意义。变频发射组件性能的好坏起着至关重要的作用,发射功率的大小决定了通信的距离。利用四倍频器降低了毫米波变频组件对本振频率的要求,利用微带带通滤波器抑制了系统的杂散和谐波,利用空间功率合成技术达到了足够的发射功率,实现了性能稳定可靠的、满足中功率毫米波通信需求的8mm频段发射组件。
In the wireless communication system, increasing the communication frequency to the millimeter wave is of great importance for increasing the capacity of the channel and improving the anti-interference of the communication. The performance of variable frequency transmitting components play a crucial role, the size of the transmit power determines the communication distance. The quadruple frequency multiplier is used to reduce the requirement of the millimeter-wave frequency conversion module to the local oscillator frequency. The microstrip bandpass filter is adopted to suppress the system spurs and harmonics. The space power synthesis technique is used to achieve sufficient transmitting power and achieve stable performance Reliable, meet the needs of medium-power millimeter-wave communications components 8mm band launch.
