Abstract
A multi-antenna transceiver system including a group of transceiver chips, and a reference frequency generator configured to provide a reference frequency for each transceiver chip. Each transceiver chip has a respective chip-associated (e.g., on-chip) frequency generator configured to provide a respective conversion frequency based on the reference frequency, wherein each respective conversion frequency is higher than the reference frequency. Each transceiver chip is configured to use the respective conversion frequency for on-chip frequency conversion of a transceiver signal. The reference frequency may be provided directly to each transceiver chip of the group or may be provided directly to a first transceiver chip of the group and to a second transceiver chip of the group via the first transceiver chip. The multi-antenna transceiver system may also include baseband processing circuitry configured to process transceiver signals for the transceiver chips, wherein the baseband processing circuitry may be further configured to estimate a first respective phase shift of each respective chip-associated frequency generator, and compensate the transceiver signals based on the first respective phase shifts.
