Abstract
The S-band receiver for Low Earth Orbit satellite is designed and fabricated as engineering model. Demodulator is implemented by using FPGA for extension of demodulator method. The receiver consists of RF Block, Digital demodulator and Power stage and has a Doppler tracking function to compensate a frequency shift that occur on the operation. The measured results of fabricated receiver show BER of less than $\small{1.0{\times}10^{-6}}$ at -110dBm RF input power and equipped a frequency tracking of $\small{{\pm}100KHz}$ relative to the center frequency. TID test was satisfied with the results of the test criterion is 10krad.
