Abstract
A wireless transceiver including: antennas, components forming transmit and receive chains coupled to the antennas for MIMO communications, voltage sources, power amplifier supply voltage detectors and regulated switches. The components forming the transmit chains include power amplifiers (PA)s each coupled to a corresponding one of the transmit chains for amplifying RF signals of a MIMO communication link and each PA having a supply voltage input. The PA supply voltage detectors each couple to an associated one of the transmit chains to detect changes in an amplitude of the signal thereon and to identify required changes in the supply voltage level of the corresponding PA for transmission of the signal. The regulated switches couple the voltage sources and PAs, and are responsive to each PA's supply voltage detector to switchably couple the supply voltage input of each PA to the voltage sources providing the identified voltage levels during transmission.
