Abstract
Embodiments of the disclosure are drawn to apparatuses and methods for transmission beamforming. A multiphase beam steering transmitter may include a transmitter array of multiple transmitters. A transmitter may include a multiphase logic decoder that directly controls a power amplifier to perform a vector addition of a beam phase and amplitude. A transmitter of the array may include a multiphase clock generator that outputs basis phases with embedded phase modulation data which are output to the multiphase logic decoder. The multiphase clock generator may receive a modulated clock signal. The PA may be a multiphase switched capacitor power amplifier. The multiphase logic decoder may output two phases adjacent to a desired phase as inputs to clocks of the SCPA. The multiphase logic decoder may further output a control signal that determines which cells in the SCPA are activated and when.
