RADIATION-RESISTANT FREQUENCY-SELECTIVE MODULES BASED ON SURFACE ACOUSTIC WAVES FILTERS
The article is devoted to the constructive-technological characteristics of construction of the radiation-resistant UHF frequency-selective modules based on surface acoustic waves filters. The results of development of the two modules on 664 MHz and 1330 MHz frequencies providing a high out-of-band selectivity (45-70 dB), transmission ratio 11-13 dB, noise figure not exceeding 7 dB are presented.
