Microstrip passband filters with low losses in the passband for the low-noise amplifier and microstrip passband filters for the diplexer of the combined bandwidth receiver of the space navigation systems "GLONASS" and "GPS" have been developed. Microstrip passband filters of the combined bandwidth L2 + L3 for the systems "GPS" and "GALILEO" have also been designed. The filters are fabricated using quarter-wave microstrip resonators. The filters have been subjected to thermal tests at temperatures from plus 70 to minus 50 °C. The serial production of the filters has been started.
