1-dB Compression Point (Out Of Band) is measured by feed a Continuous wave Tone below the lowest HPF cut-off frequency (50 kHz).
The analog IF stages include high-pass filtering, with two independently configurable first-order high-pass corner frequencies. The set of available HPF corners is summarized as follows:
Available HPF Corner Frequencies (kHz)
HPF1 HPF2
175, 235, 350, 700 350, 700, 1400, 2800
The filtering performed by the digital baseband chain is targeted to provide:
  • Less than ±0.5 dB pass-band ripple/droop, and
  • Better than 60 dB anti-aliasing attenuation for any frequency that can alias back into the pass-band.
Below +3dBm, there may be SNR degradation. Below -10dBm, there may be TX power level drop.
Cascading feature is available only in AWR1243P variant.

Figure 5-1 shows variations of noise figure and in-band P1dB parameters with respect to receiver gain programmed.
