Abstract
A calibration signal generator for use in a balancing circuit calibration device in a radio receiver, the calibration signal generator comprising: a means of amplifying a clocking signal from a clocking signal generator to provide a first calibration signal; a means of generating a second calibration signal from the clocking signal, the first and second calibration signals being transmissible to a one or more mixing circuits in the balancing circuit calibration device; and a means synchronizing the operation of other circuit elements in the balancing circuit calibration device with the clocking signal; characterized in that the clocking signal generator is present in the radio receiver and used therein for other functions.
