IWRL6432: Is it possible to bypass IF filter before ADC

I'm using CW mode of IWRL6432 and want to check doppler signal of a moving object. The signal of interest is about 0~ 5kHz and was filtered out by HPF.

The comments on HPF setting in dfp_sensor.h is like:

/*!* @brief  Chirp Profile HPF corner frequency. This is a common HPF corner frequency value* for all chirps in a frame.  \n* | Value| Definition |* |---------|----------- |* | 0| 175kHz HPF corner frequency |* | 1| 350kHz HPF corner frequency |* | 2| 700kHz HPF corner frequency |* | 3| 1400kHz HPF corner frequency |* Valid Range: 0 to 3*/UINT8 c_ChirpRxHpfSel;

Is it possible to bypass the IF filter before ADC ? 

Chris Meng：

你好，

不能。

CW模式一般用于射频测试，请注意芯片温度是否超过spec。

Thanks，

所以

1. IWRL6432 芯片内置的中频滤波器 最大的带通范围 是 175kHz~ 5MHz 是吗？ 而且没法配置旁路。 

2. IWRL6432 不建议工作在 CW 模式，如果长期CW模式会导致芯片过热。

是这样吗？
