Patent ID: 10666311

Abstract:
A multi-amplifier power management circuit and related apparatus are provided. The multi-amplifier power management circuit includes a transceiver circuit and an amplifier circuit, which are physically separated (e.g., in different integrated circuits). The amplifier circuit receives a radio frequency (RF) signal from the transceiver circuit and splits the RF signal into a number of RF transmit signals. The amplifier circuit includes a number of amplifiers configured to amplify the RF transmit signals. In examples discussed herein, the multi-amplifier power management circuit can be provided in an apparatus (e.g., a mobile communication device). The amplifier circuit may be collocated with a number of transmit antennas closer to an edge(s) of the apparatus. By collocating the amplifier circuit and the transmit antennas closer to the edge(s) of the apparatus, it may be possible to reduce RF signal radiation distance, thus helping to improve radiation efficiency and reduce heat dissipation in the apparatus.
