A 19–26 GHz balanced amplifier in 130 nm CMOS technology
Bibliographic record
Abstract
The design of a fully integrated balanced amplifier implemented in a 130 nm CMOS technology is described in this paper. This balanced amplifier achieves a gain of 30 dB from 19 GHz to 26 GHz. To reduce the signal loss and the physical dimensions of the 90° coupler utilized in this balanced amplifier, a meandered broadside coupler with shield is designed. This on-chip 90° coupler occupies a compact area of 300 um × 120 um. An effective technique based on tuning the width of the transistors to achieve wideband operation is also proposed in this paper. The proposed balanced amplifier design achieves an IIP <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> of -6.0 dBm and an input 1-dB gain compression point of -16.5 dBm. The OIP <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> and the output 1-dB gain compression point are 24.0 dBm and 10.7 dBm, respectively.

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; both teacher heads agree on what is shown here.
