A 1 V, 8 GHz CMOS integrated phase shifted transmitter for wideband and varying envelope communication systems
Bibliographic record
Abstract
A novel fully integrated phase shifted (PS) transmitter is presented in this paper. The PS transmitter employs switching power amplifiers, operates without mixers and provides an intermodulation distortion free output spectrum making it a suitable choice for mobile communication systems. The RF blocks of the PS transmitter include a local oscillator, phase shifters, switching class F power amplifiers and wideband output combiners. The PS transmitter is implemented in a standard 0.18 /spl mu/m CMOS technology, with 1 level of polysilicon and 6 levels of metallization, and occupies an area of 5000/spl times/1000 /spl mu/m/sup 2/. It operates from a 1 V supply and provides 35 dBc adjacent channel power ratio for output bandwidths up to 50 MHz at 8 GHz. The combined class F PAs in the PS transmitter provide 20 dBm output power with a 38% power added efficiency.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
