I would like to set -3dB corner frequency higher than 27.5MHz which is presented in Table 10 row 4 in datasheet. Could you please describe how to configure LTC6601-1 and external CR components? The reason for this request is that I would like to design BPF of which center frequency is at 27.12MHz. HPF will be placed in front of or back of LTC6601-1. -3dB corner frequency of LPF at 27.5MHz seems to be lower than expected.
Another question is in the equation to obtain f-3dB which is presented in Figure 3. Basic Filter Topology and Equations in datasheet. The equation seems to be wrong. Please refer to attached spreadsheet. Could you please present correct equation?
Please remove previous spreadsheet from this thread. Unnecessary sheets are included.And please refer to this spreadsheet.
