5.1 Requirements for Operating in the EU and UK regions

The following requirements must be met when operating the AWR2944EVM in the EU and UK.
  • The tested operating bandwidths for Radio Equipment Directive 2014/53/EU and UKCA compliance are 900MHz (77.45GHz center frequency) and 3900MHz (78.95GHz center frequency). The maximum peak EIRP is approximately 37dBm for the 900MHz bandwidth and 34dBm for the 3900MHz bandwidth.
    1. If users choose to operate the EVM outside of the specified operating bandwidth and operating power as described above, then the EVM must be operated inside a shielded chamber.
  • When operating in the 77GHz to 81GHz region, users must not enable more than one simultaneous TX for 0dB backoff or enable a minimum of 10dB TX backoff for multiple simultaneous TX to meet the -3 dBm limit for mean power spectral density.
  • The automotive Ethernet PHY (U4) and port (J4) on the AWR2944EVM have not been tested by Texas Instruments to be compliant with any regional standards such as Radio Equipment Directive 2014/53/EU. If users wish to populate the components necessary to utilize this port, then users can do any necessary testing to verify that the port is compliant with all applicable regional standards before use. Any modifications done to enable the J4 port invalidate the existing RED 2014/53/EU certification of the AWR2944EVM.
  • The RJ45 port (J9) has been tested to be compliant with the Radio Equipment Directive 2014/53/EU and UKCA requirements using an unshielded, symmetrical indoor CAT5 or higher Ethernet cable with a maximum length of 3 meters. If users wish to operate the AWR2944EVM with an Ethernet cable that does not meet these specifications, then users can do any necessary testing to verify that the AWR2944EVM and Ethernet cable is compliant with all applicable regional standards before use.
  • The AWR2944EVM has been tested to be compliant with the Radio Equipment Directive 2014/53/EU and UKCA requirements using a DC power cable with a maximum length of 3 meters. If users wish to operate the AWR2944EVM with a longer DC power cable length, then users can do any necessary testing to verify that the AWR2944EVM and DC power cable is compliant with all applicable regional standards before use.
  • The AWR2944EVM has been tested to be compliant with the Radio Equipment Directive 2014/53/EU and UKCA requirements using a USB cable with a maximum length of 3 meters. If users wish to operate the AWR2944EVM with a longer USB cable length, then users can do any necessary testing to verify that the AWR2944EVM and USB cable is compliant with all applicable regional standards before use.

  • The AWR2944EVM has not been assessed for the interactive control of a vehicle and any such use requires an additional assessment of applicable functional safety of the vehicle’s control systems.
