MULTI-BAND RADIO FREQUENCY MODULATOR

PROBLEM TO BE SOLVED: To provide techniques that allow operation according to two or more different communication modes in a single modulation path of a variable radio frequency (RF) modulator within a multi-mode wireless communication device (WCD).SOLUTION: The multi-mode WCD may detect a service signal from a base station within a wireless communication system and select a communication mode in which the multi-mode WCD may operate based on the communication mode of the detected service signal. A digital controller within the RF modulator can set parameters of variable components along the single modulation path of the RF modulator based on the selected communication mode. In this way, the single modulation path of the variable RF modulator may be set to process a baseband signal from a user of the WCD according to the communication mode in which the multi-mode WCD is operating.
