Active‐inductor‐matched 6‐GH<scp>Z</scp>duplexer‐less LNA/PA design incorporated with a bondwire‐antenna
Bibliographic record
Abstract
Abstract This article presents a correction to a previously published duplexer‐less LNA/PA circuit incorporating a bondwire antenna showing the comparison between the calculated, simulated, and measured results of the gain, radiated power, radiation pattern, and the transmitter to receiver link‐budget for a bondwire‐antenna for short‐range radio communications in the 6‐GHz frequency range.The correction is given in the radiation efficiency and power transmitted by the PA. The LNA and PA were matched to the 50‐Ω ports of the measuring instruments via an active inductor. Besides the inductive bondwire antenna, the LNA and PA are designed to be completely inductor‐less, thus, saving the silicon chip area. The transceiver range is calculated to be about 4.72 m, ideal for applications such as remote controls, biomedical monitoring equipment, or RFID tags. Both front end blocks are designed with low‐power, low cost, and high yield considerations for production in industry. The inductorless LNA parameters at 6 GHz are S 21 of 14 dB for both the LNA and PA, a deduced NF of 4.9 dB for the LNA, S 11 and S 22 less than −10 dB, with 10‐mW TX, and 15‐mW RX power consumption for a 1.2 V supply. © 2011 Wiley Periodicals, Inc.

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.
