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.

(3)

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 Users Guide.

(4)

The phase noise numbers use the following configuration: SYNTH ICP TRIM = 3 , SYNTH RZ TRIM = 8 , and APLL ICP TRIM = 0x26.

(5)

Cascading Feature is available in AWR2243P variant.

(6)

At 140°C TJ, the max input level recommended is 3 dBm

These values are based on a JEDEC-defined 2S2P system (with the exception of the Theta JC [RΘJC] value, which is based on a

JEDEC-defined 1S0P system) and will change based on environment as well as application. For more information, see these EIA/

JEDEC standards:
