您好!我采用 CC2642R 作为主控 。如下图,红色框图内的电路我采用单端阻抗 50 ohm 设计,绿色框图内的电路我采用差分阻抗100ohm ,是否正确?不对的话,应该怎样?

图中蓝色的部分是标准的50欧姆:
巴伦部分建议完全按照参考设计,要使用单端可以参考下面的射频前端部分和后面的说明:
There are designs that cannot use the reference design as is (for example, use of a different component
size). In this case, it is recommended to simulate both the TI reference design and the customer design in
ADS. The two designs should have the same S21/ S22.

• Differential External Bias target load impedance: 45 + j43 Ω
• Differential Internal Bias target load impedance: 42 + j21 Ω
• Single-ended Internal Bias target load impedance: 38 + j5 Ω
您好!这个链接下载的压缩包,有没有 Layout 源文件 的?解压时提示发生错误,只解压了一部分,没有找到 Layout 源文件 。
