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 Si4012 differential output resistance should equal 600
