Abstract
A TV-band white-space transmitter covering a 16x-wide spectrum from 54 to 864 MHz is described. It features a systematic codesign between the architecture and circuits to ad- dress the harmonic-mixing problem. Speci fically, it incorporates two-stage 6-/14-path harmonic-rejection mixers and low-Q pas- sive-RC/-CLC filters to manage the unwanted harmonic emission fully on chip, achieving an uncalibrated harmonic rejection ratio (HRR) of minimally 59.3 dB (16 samples) for all in-/out-band harmonics.
