3.8 Typical Layout Problems and Solutions
3.8.1 Q: The voltage ripple is not large, but the TX performance of RF is rather poor.
3.8.2 Q: The voltage ripple is small, but RF TX performance is poor.
3.8.3 Q: When ESP32-H2 sends data packages, the power value is much higher or lower than the
target power value, and the EVM is relatively poor.
3.8.4 Q: TX performance is not bad, but the RX sensitivity is low.
