Abstract
A CDMA transmitter having a variable gain circuit inserted between a transmitter mixer and a transmitter antenna. The gain is controlled in response to the RF output power so that the spurious emission level at the maximum RF output power and that at output power reduced by a predetermined amount can be both satisfied. This makes it possible to increase the degree of freedom of choosing circuit components in the RF stage.
