Notes:
1. The frequency range is continuous over the specified range.
2. The frequency step size is limited by the frequency noise.
3. Optimum differential load is equal to 4 V/(11.5mA/2 * 4/PI) = 550 　Therefore the antenna load resistance in
parallel with the RF60 differential output resistance should equal 600　
4. Total NVM copy time = 2 ms + (NVM copy Boot Time per kB) x (NVM data in kB).
