Such a rate is easy to achieve, even with old chips, but there is an additional burden when using Class D modulation.
这样的频率即使是用旧的芯片也很容易实现，但是当使用D类调制时会产生额外的负荷。

The controller combines parallel amplification and drain modulation of the CMOS class-E power amplifier to provide high efficiency over a broad range of output powers.
