Frequency-selective microblocks based on SAW-filter chips
DESCRIPTION
Frequency-selective microblocks based on surface acoustic wave (SAW) filters, intended for use in radio electronic equipment (REA) as the main functional elements for the formation of amplitude-frequency and phase-frequency characteristics of the radio-frequency path. The use of a new circuit solution of microblocks, original designs of SAW filters and methods of their calculation allowed more than 2 times to expand the range of operating frequencies of microblocks (up to 1330 MHz) and bandwidth (up to 9%) in comparison with existing analogues and realize high out-of-band selectivity 45-70 dB), transmission factor 10-15 dB and high noise immunity.
