High Performance CATV Converter

In the present typical CATV systems in the U.S., carrier frequencies for 64 channels are in the range of 54 to 444 MHz. Recently, a99 channel plan has been reported by EIA as shown in Fig.1. Under these circumstances, one of the most difficult problems in CATV converters is to decrease the intermodulation distortions among channels without any degradation in noise performance.
