The scheme of GLONASS receiver is designed based on the principle of high-frequency circuit. The circuit of the receiver can be divided into three parts listed as follows: signal amplification, intermediate frequency separation and generation of coherent carrier. And its main elements are microwave integrated circuit amplifier BGA2001, the high frequency filter TA0676A, broadband direct conversion quadrature demodulator AD8347 and dual-band RF synthesizer with integrated VCOs Si4123. The designed receiver should be able to receive GLONASS L1 signal.
