Why is current consumption during receive higher than transmit?

The XBee manual says that the current consumption during transmit is 45mA whereas it is 50mA during receive.

Just wanna clarify that receive means that the XBee is either listening on a clear channel with no incoming signals, or actively receiving and decoding a signal. Correct?

Main question is, how come the current consumption is higher during receive? Shouldn’t it be higher during transmit?

Hey according to theoretical definition you are right for normal RF communication, e.g. Cellular, where at one side is the high gain dipole antenna. But here in case of xbee both side the low gain antenna are equipped. Therefore this difference is being shown. I hope this answers your question.
