Abstract
A design methodology for front ends of a Direct Broadcasting satellite (DBS) Receiver for X-band was reported by utilizing Monolithic Microwave Integrated Circuits (MMIC) technology. The frequency converter including a three-stage low-noise amplifier, a image frequency rejection filter, and a mixer and buffer amplifier was designed by a Home-made CAD program. The results of computer simulation using the CAD program showed that overall gain was over 36.63dB, and noise figure below 2.55dB, respectively.
