1. A multi-antenna transceiver system comprising:
a group of transceiver chips, wherein each transceiver chip has a respective chip-associated frequency generator configured to provide a respective conversion frequency, and wherein each transceiver chip is configured to use the respective conversion frequency for on-chip frequency conversion of a transceiver signal; and
a controller adapted to cause configuration of the respective chip-associated frequency generator of at least one of the transceiver chips, wherein the configuration comprises dynamically setting the respective conversion frequency, wherein the controller comprises at least one respective piece of circuitry comprised on at least one of the transceiver chips, and wherein the respective piece of circuitry is adapted to cause configuration of the respective chip-associated frequency generator of at least the transceiver chip on which it is comprised.
