Abstract:
A system and method for tuning baseband filters in wireless transceivers. A method comprises coupling a radio frequency (RF) signal generated by the wireless transmitter at an input of a wireless receiver, the RF signal having a desired frequency, measuring a magnitude of the coupled RF signal at an output of an analog-to-digital converter at an output of an analog baseband filter, wherein the magnitude is measured at the desired frequency, and adjusting a corner frequency of the analog baseband filter in response to the determining that the measured magnitude differs from a specified value.
