Electronic Monitor for Cars

Takafumi Tsuji; Toshiki Miyasaka; Makoto Yoshida; Masaharu Baba

An electronic monitor for car use using a 5.9-inch diagonal full color TFT-LCD (Thin Film Transistor Liquid Crystal Display) has been newly developed and is now being manufactured. The LCD monitor has several merits when compared to a CRT (Cathode Ray Tube) monitor: reduced dimensions (especially in its depth), lighter weight and lower power consumption. This paper introduces the LCD monitor and the technologies developed for each of its elements: the new LCD panel, the back light system, the signal processing circuit and the temperature compensation technology.

A 12 GHz Low Noise Converter for Two Band Reception

Hiroyasu Miura; Shigeo Ogawa; Toshiki Miyasaka

A 12 GHz low, noise converter (LNC) suitable for use in two band reception has been developed. A wideband, very low noise amplifier (LNA) and two Switchable local oscillators in the LNC make it possible to receive two frequency bands. The developed LNC has low noise figures of less than 2.5 dB (for frequency band from 11.7 to 12.2 GHz) , a high image rejection ratio of more than 90 dB, and very low local power leakage of less than -95 dbW.
