IMT-2000 단말기용 Dual PLL 설계 및 제작
Design and Fabrication of Dual PLL for IMT-2000 Cellular Phone
초록
This paper describe the design and measurements of dual PLL for IMT-2000 cellular phone. As a result, dual PLL was well-operated in the RF frequency ranges of 2300 ~ 2360 MHz and If frequency of 380 MHz. The output power of -4.28 ㏈m, phase noise of -107.66㏈c/Hz at 100KHz frequency offset, lock time of 675.6
