The third-order harmonic distortion can be reduced by using

required values for R
(single tone) third-order distortion reduction at 180 MHz.
Figure 23 and Figure 25 show any gain (up to 18 dB) vs. C
200 Ω and 1 kΩ loads, respectively. When these values are selected,
they result in minimum single tone, third-order distortion at
180 MHz. This frequency point provides the best overall broad-
band distortion for the specified frequencies below and above
this value. For applications above ~300 MHz, C
not required. See the Specifications section and the third-order
harmonic plots for more details (see Figure 12, Figure 14, and
Figure 15).
C
below 180 MHz that result in relatively lower third-order (in-
band) intermodulation distortion terms. See the Narrow-Band,
Third-Order Intermodulation Cancellation section for more
information. Though not shown, single tone, third-order
optimization can also be improved for narrow-band frequency
applications below 180 MHz with the proper selection of C
and 3 dB to 6 dB of relative third-order improvement can be
realized at frequencies below approximately 140 MHz.
