This broadband optimization was also performed at 180 MHz.
As with differential input drive, the resulting distortion levels
at lower frequencies are based on the CD and RD specified in
third-order reduction improvement at frequencies below
140 MHz is realized with proper selection of CD and RD.

NARROW-BAND, THIRD-ORDER
INTERMODULATION CANCELLATION
Broadband single tone, third-order harmonic optimization does
not necessarily result in optimum (minimum) two tone, third-
order intermodulation levels. The specified values for CD and
broadband, single tone third-order levels.
Due to phase-related distortion coefficients, optimizing single
tone third-order distortion does not result in optimum in-band
(2f1 f2 and 2f2 f1), third-order distortion levels. By proper
selection of CD (using a fixed 4.3 kΩ RD), IP3s of better than
45 dBm are achieved. This results in degraded out-of-band,
third-order frequencies (f2 + 2f1, f1 + 2f2, 3f1 and 3f2). Thus, careful
frequency planning is required to determine the trade-offs.
Figure 32 shows narrow-band (2 MHz spacing) OIP3 levels
optimized at 32 MHz, 70 MHz, 100 MHz, and 180 MHz using
CD value and associated OIP3 levels) are extrapolated to provide
close estimates of OIP3 levels for any specific frequency between
30 MHz and 180 MHz. For frequencies below ~140 MHz, narrow-
band tuning of OIP3 results in relatively higher OIP3s (vs. the
broadband results shown in Table 2 of the specifications). Though
not shown, frequencies below 30 MHz also result in improved
OIP3s when using proper values for CD.
