Abstract
For example, an apparatus may include a Local Oscillator (LO) generator configured to generate a distributed modulated LO signal by modulating an LO signal based on a reset signal; and a plurality of Physical Layer (PHY) chains to receive the distributed modulated LO signal, which is distributed to the plurality of PHY chains by the LO generator, a PHY chain of the plurality of PHY chains including a reset detector configured to detect the reset signal based on the distributed modulated LO signal, and, based on a detection of the reset signal, to reset one or more Radio Frequency (RF) elements of the PHY chain.
