A Current-Mode Multiphase Digital Transmitter With a Single-Footprint Transformer-Based Asymmetric Doherty Output Network

This article introduces a current-mode multiphase digital transmitter with a single-footprint transformer-based asymmetric Doherty output network. The proposed multiphase architecture overcomes the bandwidth expansion associated with the polar power amplifier (PA), while still achieving relatively c...
