description: The object of the study are the frequency-selective devices of the receiving path of wireless infocommunication systems. The aim of the work is the synthesis and implementation of frequency-selective devices of the receiving path of wireless infocommunication systems, including: miniaturized microstrip bandpass filters with enhanced selectivity on coupled resonators, complex filters with an extended dynamic range. A method has been developed for the synthesis of microstrip bandpass filters based on coupled resonators, which makes it possible to realize filters based on quasi-elliptic approximation. A technique for the synthesis of complex filters of high order based on the reactance transformation was developed, the correctness of the technique was confirmed by the results of modeling. A transconducting amplifier with a low level of nonlinear distortion is realized, on its basis a fifth order filter with an extended dynamic range is synthesized. Experimental samples of microstrip bandpass filters of the S-band were made, their S-parameters were measured. The results of measurements confirm the correctness of the developed procedure.
