Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the inexpensive PLL module which can output a signal of stable high frequency of 3 GHz or higher. SOLUTION: The PLL module 11 is constituted by combining a PLL-IC 4 having frequency dividers 5 and 6 and a phase comparator 7 inside, a loop filter 8, and a voltage-controlled oscillator 9, and a multiplexing circuit 12 is provided at its output to constitute the PLL module 11. Consequently, signal source for a stable high frequency of 3 GHz or higher can be obtained at low cost.
