Single-band TV signal shaper tuned over wide frequency range

摘要

A possibility of manufacturing a single-band TV signal shaper tuned over a wide frequency range is considered. The possibility of a single-band frequency-switched TV signal shaping offers interchangeable channels, headend channel transformation and the resulting broader market access. The emergence of mobile communications systems has boosted the development of SAW technology and refined its calculation techniques. The intermediate frequency (IF) has increased, which offered the opportunity of designing a single-band TV signal shaper tuned over a wide frequency range. The creation of an above-250 MHz SAW filter with a right slope performance offers a wider frequency tuning for modulators, at the same time keeping the device relatively simple.
