Abstract: The microwave integrated doubler link used in satellite engineering is of low noise, excellent stability, high efficiency or low comsupsion and exparided width for c band. It has an ability to simultaneously output four channel signal of same amplitude,constant frequency and unity phase. The output of each channel has less than-70dB for noise, and more than 65dB for the harmonic suppression. It consists of a sixty-time(4×4)doubler used a jump-diode with non-idler circuit, a two stage power-amplifier used the non-insulation and a power divider of about-6dB. The max efficiency of the jump-diode for four-time doubler is more than 56%;the gain of power amplifier is 8dB and 17dB respeetively; the divider has properties that the insulation between each twoterminal is more than 20dB and the balancing degree is about 0.1dB. They had respectively assembled in two box resonator of size 230×58×33(mm)and 58×38×24. Total weight is about 0.9kg.
