Abstract
The analog front-end in a wireless transceiver acts as the interface between the antenna and the digital signal processor. In the digital signal processor, low power is essential, making submicron CMOS technology the best implementation choice. The analog front-end and specifically the low noise amplifier (LNA) require a high speed technology, such as GaAs or silicon bipolar. However, the use of low-cost submicron CMOS or SOI CMOS technology in the analog front-end may lead to an optimum single chip implementation of both the analog and digital building blocks in wireless transceivers used in modern high capacity mobile communication systems. Such an implementation offers reduced cost and improved reliability. This paper describes a 1 V, 0.5 /spl mu/m SOI CMOS LNA optimized for CDMA applications and operating in the 1.93-1.99 GHz band. Compared to previously reported designs (Johnson et al., 1998; Komurasaki et al., 1998; Jin et al., 1999; Harada et al., 2000), this design offers lower noise, high gain, low intermodulation distortion and on-chip 50 /spl Omega/ input output impedance matching.

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 it
