Murata Mfg Co. Ltd has announced the development of a compact digital CATV tuner that measures 50-by-41-by-12mm - 40 percent smaller than the company's conventional models.

Intended for use in digital cable STBs and TV receivers for the North American market, the tuner achieves its compact size through the use of dedicated ICs in the first and second mixer stages, as well as using a smaller circuit configuration.

In addition to the size reduction, the tuner incorporates a diplexer circuit for bidirectional communication and a splitter circuit for signal distribution to other tuners. The splitter circuit uses a low-noise amplifier circuit that exhibits a mutual modulation distortion of <70dB, thereby reducing image quality deterioration due to signal distribution.
