Abstract
A tuner station apparatus includes a first mixer for combining an input signal and a first local oscillation signal, and a second mixer for combining an output of the first mixer and a second local oscillation signal. The first and second local oscillation signals are generated by first and second PLL circuits, respectively. Each of the first and second PLL circuits include a frequency divider, a variable frequency divider, a phase comparator, a low pass filter, and a voltage controlled oscillator. The frequency divider of the first PLL circuit has a higher frequency division ratio than that of the second PLL circuit.
