ABSTRACT:
A transmitter having an automatic power controller (APC). The APC switches the output power of the transmitter in a plurality of steps by gain control. The APC selects a desired one of a plurality of mutually independent variable voltage sources in accordance with an external command to obtain the offset voltage. The offset voltage is used for the gain control. The APC also can finely adjust the voltage output from the variable voltage sources in accordance with the external command independently of the other variable voltage sources.
