Abstract
The very small sized and light weighted satellite receiving converter with excellent characteristics has been developed for the Ku-band. The very low noise FET mixer is newly developed and used for the converter. Because of the realization of the low noise FET mixer, the excellent characteristics of the converter with two-stage low noise amplifier which is composed of the HEMT and the FET are obtained. In addition, the special strip-line corner is developed and applied in order to make the converter size smaller. The characteristics of the converter with these technologies are the noise figure of 1.7dB max, the conversion gain of 55dB min and the image rejection ratio of 50db min. Total power consumption of the converter is 1.7w. The converter are particulary very small volume of 100cc and light weight of 180g.
