(1)

1-dB Compression Point (Out Of Band) is measured by feed a Continuous wave Tone well below the lowest HPF cut-off frequency.

(2)

The analog IF stages include high-pass filtering, with configurable first-order high-pass corner frequency. The set of available HPF

corners is summarized as follows:

Available HPF Corner Frequencies (kHz)

175, 350, 700, 1400

The filtering performed by the digital baseband chain is targeted to provide less than ±0.5dB pass-band ripple/droop.

Figure 7-6 shows variations of noise figure and in-band P1dB parameters with respect to receiver gain

programmed.
