    Abstract: Techniques are provided for configurable millimeter wave (mmWave) receiver architectures for carrier aggregation (CA). An example method for operating a wireless node in a carrier aggregation mode or a single band mode includes configuring the wireless node to operate in at least one of the carrier aggregation mode or the single band mode, configuring a high band receive chain wireless node to utilize a first intermediate frequency in response to configuring the wireless node to operate in the single band mode, and configuring the low band receive chain to utilize the first intermediate frequency, and the high band receive chain to utilize a second intermediate frequency in response to configuring the wireless node to operate in the carrier aggregation mode.

    Abstract: The present disclosure provides an apparatus that includes a first mixer circuit configured to convert between an RF signal and an IF signal based at least in part on an local oscillator (LO) signal. The first mixer circuit is electrically coupled to a first node that is configured to receive the LO signal and a first bias voltage, a second node that is configured to receive the RF signal or the IF signal, and a third node that is configured to provide the IF signal or the RF signal. The apparatus further includes a second mixer circuit electrically coupled to a fourth node configured to receive the LO signal and a second bias voltage, the second node, and the third node. The second bias voltage has a voltage level that is offset from the first bias voltage.
