AWR2243: Rx gain

KenF

Part Number: AWR2243

Hello experts,

I have two questions.

(1) Rx gain in the datasheet is Voltage gain, not Power gain, right?

(2) If the answer of (1) is "Voltage gain", is it gain from LNA input to ADC input?

Best regards,
Ken

Hello Ken,

This is Power gain.

The RX gain is the gain of the complete RX chain, including LNA, VGA etc. Hence, the number specified in the datasheet comprises of the total gain from the LNA input to the ADC input (dBm).
