<p>A transmitter including a first mixer, a first frequency divider to divide a frequency of an input signal to generate a first signal, and a plurality of second frequency dividers to divide the frequency to respectively generate a plurality of second signals, and a control module. In response to the transmitter being turned on, the control module turns on the first frequency divider, turns off the plurality of second frequency dividers, and drives the first mixer with the first signal. Subsequently, in response to determining that a transmit power of the transmitter is to be increased, the control module sequentially turns on and connects each of the plurality of second frequency dividers in parallel to the first frequency divider. Upon a second frequency divider being connected to the first frequency divider, the control module also drives the first mixer using the second signal generated by that second frequency divider.</p> |
