射频合成器凭借其内部锁相环,从单个(通常较低)的参考频率生成宽范围的高频率。 通过 SPI 接口访问器件中的数字寄存器来控制输出频率。 输出频率是由相对于输入信号的分数或整数比率产生的。
瑞萨电子提供具有超低相位噪声和低杂散的射频合成器,这可解决射频板设计中高性能混频器、调制器和解调器的频率生成难题。 射频合成器还可用于直接为高速射频转换器 (ADC/DAC) 提供时钟参考。 输出频率范围包含低 MHz 至 18GHz。
此类器件带有集成式压控振荡器 (VCO),并具有较大的调谐范围,可提供多频段本机振荡器 (LO) 频率合成,从而能够减少对多个窄带射频合成器的需要。 这降低了物料费用和设计复杂性,同时也降低了开发射频产品的成本。 其提供各种解决方案,可以应对射频板设计中高性能混频器和解调器的频率生成难题。
