大家好,
我正在设计一个基于 ESP32-C6(QFN40 封装)的射频前端电路。目前我正在构建 LNA_IN 引脚的匹配网络,以实现 2.4 GHz 频段下的最佳匹配(VSWR ≈ 1)。
为了进行准确的仿真匹配网络,我需要知道芯片内部 LNA 输入端口(LNA_IN)的复阻抗(Z = R + jX),特别是在 2.4 GHz 时的阻抗值。
我已经查阅了 ESP32-C6 的 Datasheet 和参考设计,但没有找到该引脚的阻抗参数。请问:
1. 官方是否有提供 LNA_IN 引脚在 2.4 GHz 下的复阻抗?
2. 是否有推荐的匹配网络参考值用于该引脚?
3. 该阻抗是否与 ...

Requesting LNA_IN Input Impedance for ESP32-C6 (QFN40)
Hi everyone,
I am designing an RF front-end circuit based on the ESP32-C6 (QFN40 package). I'm working on a matching network for the LNA_IN pin in the 2.4 GHz band, and I aim to achieve proper impedance matching (VSWR ≈ 1).
In order to run accurate simulations, I need to know the internal input ...
