摘要： A transmitter is provided which includes a transmitting circuit that does not require a high-performance low noise VCO restricting cost reduction thereof and that can reduce the number of parts without requiring an RF filter. A direct conversion that does not require a transmission VCO is applied to the transmitting circuit. In order to achieve noise reduction in a receiving band, low-pass filters are provided at IQ input sections of a modulator that converts IQ signals into RF signals. In comparison with a conventional transmitter using offset PLL, an external VCO required in addition to an RF integrated circuit, a power amplifier, and a front end circuit is reduced. Even in current transistor performance, by using a filter having rapid waveform characteristics such as a SAW more inexpensive than the VCO, or the like, it is possible to provide a GSM/GSM 1800/GSM1900 triple band transmitter.

摘要： To solve an overlap between a part table and components automatically and adequately in a drawing using a CAD. In a part table creating method for creating a part table including a plurality of rows of CAD data, an overlap between the part table and other geometric elements is detected. When the overlap is detected, the height of the respective rows of the part table is reduced to H1. When the overlap between the part table and the other geometric elements still remains even when the respective rows of the part table is reduced to the height H1, the number of overlapped rows between the part table and the geometric element are obtained. The portion of the overlapped rows is separated and moved in the direction to avoid the overlap with the geometric elements to separate into an original part table and a destination part table.

A communication semiconductor integrated circuit has a plurality of low-pass filters and variable gain amplifiers which are alternately connected in multiple stages, and high gain amplifier circuits for amplifying reception signals to a predetermined amplitude level.
