Abstract
A transmitting apparatus for code division multiplexed signals used in the spread spectrum communication has its analog amplifier rid of spurious generation and relieved of the need of having a large transmission back-off, thereby accomplishing the low-power, low-cost and simple design of the amplifier. Multi-channel transmission signals are rendered the spread spectrum with a spread code, and the resulting code division multiplexed signal undergoes the peak amplitude limitation so that the last-stage analog amplifier can have a small back-off.
