2.4.9 Voltage Rails Ripple Measurement Connectors (J1, J5) (DNP)
J1 Provides access to measure ripple on 1V0_FILTERED (1.0 analog RF supply for AWR2944) voltage rail.
J5 Provides access to measure ripple on 1V8_FILTERED (1.8-V analog supply for AWR2944) voltage rail.
These connectors are not populated on the board by default. To populate these connectors with the appropriate
part, please refer to the Schematic, BOM, and assembly files.
2.5 Antenna
The AWR2944EVM includes onboard etched antennas for the four receivers and four transmitters, which
enables tracking multiple objects with their distance and angle information. This antenna design enables
estimation of both azimuth and elevation angles, which enable object detection in a 3-D plane (see
).
