摘　　要：提出了一种使用MAX2620构成宽带VCO及在此基础上与ADF4001一起构成宽带锁相频率源的设计方案并给出了电路实物及测试结果。测试表明该频率综合方案具有较宽的频率范围(45MHz～75MHz),且频谱杂散性能良好,功耗较低,具有较好的应用价值。A broadband PLL frequency source implementation is presented, in which MAX2620 is used for constructing a broadband voltage-controlled oscillator（ VCO） and it forms a PLL frequency source with ADF4001. Then the circuit and test result are given. Tests show that the implementation has a wide range of output frequency （45 MHz -75 MHz）. Also the system has a excellent performance of spurs and low-power,which makes the system to be a valuable part in wireless receivers.
