ABSTRACT:
A transmitter chain has a quadrature modulator, a variable gain amplifier, an up-converter, and a variable gain power amplifier. An overall phase of the transmitter chain is adjusted on the basis of pre-stored phase information reflecting phase changes due to simultaneous gain changes of gains of at least the variable gain amplifier and the variable gain power amplifier.
