I'm using BGT24MTR11 chip and I need to calculate VCO frequency based on tuning voltage. Vfine and Vcoarse are equal.
I have found a graph in BGT24MTR11 application note 305, but without equation I can only assume if, for example, at 25 degrees and 1.5V frequency is 24.3GHz or 24.4GHz?

Thanks in advance for any help.

Best regards,
