本文阐述了一个基本的Ｓ波段锁相式频率综合器，频率范围是２．３０ＧＨｚ～２．７０ＧＨｚ，频率步进为５ＭＨｚ，相位噪声指标为￡（１０ｋＨｚ）＜－９５ｄＢｃ／Ｈｚ，杂散抑制优于５０ｄＢ，输出功率大于１０ｄＢｍ
This paper presents a basic S-band PLL frequency synthesizer with a frequency range of 2.30GHz ~ 2.70GHz, a frequency step of 5MHz and a phase noise of £ (10kHz) <-95dBc / Hz with excellent spurious suppression At 50dB, the output power is greater than 10dBm
