(a) Cell phone signals in the range of 1.8 to 2.0 GHz are mixed with a local oscillator to produce an output signal at 70 MHz. What is the rangeof local oscillator (LO) frequencies required if the LOis belowthe cell phone signal frequency? What is the frequency range of the unwanted output signals? (b) Repeat if the local oscillator signal is above the cell phone frequency? (c) Which choice of LO frequency seems most desirable?
