The digital transmitter includes a vector decomposer circuit, a phase selector circuit, and a digital power amplifier (DPA). The vector decomposer circuit receives baseband in-phase (I) and quadrature (Q) signals and decomposes the baseband I and Q signals into an offset envelope signal and a non-offset envelope signal. The phase selector circuit receives a plurality of phase offset local oscillator (LO) signals and outputs, responsive to the baseband I and Q signals, offset LO signals and non-offset LO signals. The DPA processes the offset envelope signal, the non-offset envelope signal, the offset LO signals, and the non-offset LO signals to generate an output signal of the digital transmitter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Broadband digital transmitter using π/4 phase offset local oscillator (LO) signals","description":"A broadband digital transmitter is disclosed.
