Design and simulation of Digital Beacon Receiver has to locate the beacon signals and measure its power levels. It was designed by using Agilent Technologies, Advanced Design System (ADS) software. Some natural sources, such as full of atmosphere gases, carbon dioxide, hydrocarbon, haze, downpour, dust, mist and some other helium and nitrogen gases exists in different layers of the atmosphere, including troposphere, ionosphere can cause some obliteration on the accessibility and quality of downlink examine periods. This climate incident cause errors and difficulties, such as attenuation changes in polarization, fading delay, and dispersion. Mostly at higher band of frequencies such as Ku and Ka bands, the effects of that transmission phenomenon will not be nelegectable and they should be measured. It is a consistent and protected satellite communication. Mathematical calculations for both theoretical and experimental transmission is studied and by different frequencies. Indian Space Research Organization (ISRO) has setup two different beacon signals at 20.2 GHz and 30.5 GHz on board GSAT-14 for this explanation. There is a different method to study, accurate rain attenuation distribution and satellite wave transmission, such as radar, radiometer, signal beacon method, and satellite beacon receiver. Satellite beacon receiver is one of most important responsible and reasonably priced methods in comparison with the other methods. Digital receiver estimates the signal strength of the beacon signals at 20.2 GHz and 30.5 GHz, for both polarizations (co-polar and cross-polar amplitude measurements). This paper gives the design simulation of the receiver setup using Harmonic Balance (HB), S-Parameter, AC simulation, power budget analysis, Bandpass filter design, and Fast Fourier Transform (FFT) design simulations. The simulation results match with 98% of tested results.
