"BOXCAR" - The series narrow-band SAW filters, which have different central frequencies, with LC matching circuits of input and output is proposed . Filters Input and output is strip line.
Produced three groups of filters
| group A | 30,30…89,50 MHz | | group B | 227,45…396,30 MHz | | group С | 11,00…134,80 MHz |
