Enhanced feedback signal routing designs and methods for enhanced transceiver performance

A transceiver, comprising:

• a first transmit chain including a first power amplifier;
• a first receive chain including a first mixer and a first baseband filter;
• a first shared baseband filter coupled to a first transmit chain and the first receive chain;
• a second receive chain including a second mixer and second baseband filter;
• a second shared baseband filter coupled to a second transmit chain and the second receive chain;
• feedback circuitry including an input coupled to an output of the first power amplifier of the first transmit chain and an output coupled to an input of the first mixer of the first receive chain;
• and
• routing circuitry coupled to the first shared baseband filter, the second shared baseband filter, the first mixer of the first receive chain, and the second mixer of the second receive chain, and including multiple routing paths, the multiple routing paths including intra-chain receive signal paths and inter-chain feedback signal paths.

A method for wireless communication, comprising:

• generating, by a feedback circuit, a feedback signal based on a transmission signal of a transmit chain;
• providing, by the feedback circuit, the feedback signal to a mixer of a receive chain corresponding to the transmit chain;
• mixing, by the mixer, the feedback signal to generate a mixed feedback signal;
• and
• providing, by the mixer, the mixed feedback signal to a baseband filter of a different receive chain via routing circuitry.
