AWR2243: Minimum frequency slope

Alexander McInnes

Part Number: AWR2243

Hello,

I am trying to find out what the minimum frequency slope (i.e., maximum chirp time) is that the AWR2243 can support for a chirp. The ICD states that PF_FREQ_ SLOPE_CONST has 1 LSB equivalent to 48.279 kHz/us, so I assume this is the lowest you can make it? Is there anyway to decrease this? For example, maybe the VCO can be controlled directly to create a slower ramp?

Cheers,

Alexander

    Hello,

    Yes, your understanding is correct. The valid ranges are as below with the minimum value of 48.279kHz/us. There is no way to achieve a smaller slope value.
