IMPROVED RC FILTER POLE FOR FM TRANSMITTERS
An RC filter pole (R 1 , C 1 ) for FM transmitters converts an internal 2-pole Bessel-type filter (R 1 , C 1 , C 2 ) on a chipset (BH141XS/F) by adding an external filter function to create a 3-pole composite filter with improved roll-off characteristics. The design methodology and specific low cost...

Summary: | An RC filter pole (R 1 , C 1 ) for FM transmitters converts an internal 2-pole Bessel-type filter (R 1 , C 1 , C 2 ) on a chipset (BH141XS/F) by adding an external filter function to create a 3-pole composite filter with improved roll-off characteristics. The design methodology and specific low cost circuit implementation of the composite filter effectively minimizes the impact of signal degradation on overall link performance. |
