(1) 1-dB Compression Point (Out Of Band) is measured by feeding a continuous wave tone at 5% of the programmed HPF cut-off frequency (i.e. blocker tone). The compression point is determined by the blocker power that results in a 1dB compression of the blocker tone at the RX ADC.
(2) The analog IF stages include a second order high pass filter that can be configured to the following -6dB corner frequencies:
Available HPF Corner Frequencies (kHz)
HPF
300, 350, 700, 1400,
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.
(3) The max ramp rate depends on the PLL bandwidth configuration set using the"AWR_APLL_SYNTH_BW_CONTROL_SB" API. For more details, refer to the mmWave Radar Interface Control document.
(4) VCO2 supports a maximum continuous range of 4.5GHz. The supported range can span 76-80.5GHz or 76.5-81GHz through VCO2_RANGE_CONFIG in AWR_ CAL_MON_FREQUENCY_* API.
