(1) 1-dB Compression Point (Out Of Band) is measured by feeding a continuous wave tone below the lowest HPF cut-off frequency (10 kHz).
(3) 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.
(4) The max ramp rate depends on the PLL bandwidth configuration set using the"AWR_APLL_SYNTH_BW_CONTROL_SB" API. For more details, see the mmWave Radar Interface Control document.
(5) The phase noise numbers use the following configuration: SYNTH ICP TRIM = 3 , SYNTH RZ TRIM = 8 , and APLL ICP TRIM = 0x26.
(6) At 140°C TJ, the max input level recommended is 3 dBm
