Purpose of the development: SAW filter is used to generate amplitude-frequency characteristic (AFC) of the intermediate frequency (IF) receivers (special and household) tuners.

Recommended application field: Development can be realized by the enterprises and organizations of the Ministry of Industrial Policy of Ukraine and private industry.

Technical characteristic: Main technical characteristics of the SAW filter for the IF-FM VHF radios class ± Hi-Fi: 1. Center frequency, MHz: 10,7 ± 0,1. 2. Bandwidth 3 dB kHz: 200 ± 30. 3. Attenuation at the center frequency, which is entered in dB, not more than 14. 4. Guaranteed attenuation at the center frequency of the disorder at ± 0,42-2,00 MHz, dB, not less than 40. 5. Flatness in disorder at ± 50kHz from the center frequency, dB, not more: 1. 6. Uneven group delay in a bandwidth: 0.2.

The development stage readiness: Ready for application

Technical and economic effect: The cost of the SAW filter for IF-FM VHF tuner serial production volume of 10,000 units. year does not exceed Rs 10, which ensures high profitability.
