CC1201: Simultaneous transmission and reception for RSSI measurement

Part Number: CC1201

Tool/software:

Dear TI support,

for our product we would need functionality of measuring RSSI of signal we are transmitting and receiving at the same time. We don't need to transmit any data, so we can transmit only carrier frequency in this mode. Is this possible with a single transceiver IC please? In other words we need to measure attenuation between transmitter and receiver ports and we would like to do so with a single IC.

thank you

  • Hi,

    The CC1201 (and our other Sub-1 GHz products) are capable of Half Duplex only, so cannot transmit/receive at the same time.

    You would need to use two devices for this purpose.

    Regards,

    Zack

  • You should probably look for a dedicated RSSI or RF Power Detector, such as those proposed by AD.
