A 65-nm CMOS I/Q RF Power DAC With 24- to 42-dB Third-Harmonic Cancellation and Up to 18-dB Mixed-Signal Filtering.

A 700-MHz to 1.6-GHz RF power digital-to-analog converter with programmable integrated harmonic cancellation and mixed-signal filtering is presented. Harmonic cancellation is implemented by splitting the power amplifier (PA) into segments, driving different segments of the PA with phase-shifted versions of the local oscillator (LO) signals, and summing at the output. Mixed-signal filtering is real...
