摘要
阐述了一种Ka频段卫星通信上变频器的实现方案,采用一次变频方案将中频信号上变频至Ka频段射频信号,在实现一定增益的同时能够保证设备的杂散、相位噪声以及幅频特性等指标。该设计方法与调试技巧能够广泛应用于卫星通信地球站的上行链路。
Describes an achievement to design a kind of Ka-band up-converter, which converts S-band IF signal to Ka-band RF signal by once frequency conversion. The some gain can be achieved as well as the output spurious, phase noise and amplitude –frequency characteristics. The design and debug method can be used in up-link of satellite communications.
