AWR2243: MMWCAS-RF-EVM

Part Number: AWR2243

Hi,

Does the AWR2243 have a port that can be used to test the sensitivity of the RX received signal?

    Hello Nancy,

    Are you trying to do sensitivity measurement by feeding a known signal at the Rx input? On our EVM we do not have a waveguide interface for you to feed  a known signal in a conducted manner.

    The customer wants to do the following test. After the signal received by the RX is processed by the internal low-pass filtering of the chip, the signal before the ADC is compared with the input signal.

    Some manufacturers' chips will have special pins for this function test. I want to confirm whether the AWR2243 supports this function?

    If it is not supported, have you conducted similar tests internally, and have you reported any reports?

    Hello Nancy,

    I am not sure I understand the request fully. If we feed a 1Mhz offset tone (RF frequency + 1 Mhz) at the RX LNA input we can get a 1Mhz tone in the ADC data. Is that what you are suggesting?

    Regards,
