Note 1 – Items in min/max columns in bold italics are Guaranteed by Test.
Note 2 – Items in min/max columns that are not bold/italics are Guaranteed by Design Characterization.
Note 3 – The input 0.1dB compression point is a linearity figure of merit. Refer to Absolute Maximum Ratings section
for the maximum RF input power and Figure 1 for maximum operating RF input power.
Note 4 – F_RF = 1GHz.
Note 5 – Minimum time required between switching of states =1/ (Maximum Switching Rate).
Note 6 – Spurious due to on-chip negative voltage generator. Typical generator fundamental frequency is 2.2 MHz.
