Duplexer-less LNA/PA design for wireless transceivers with bondwire-antenna
Bibliographic record
Abstract
This paper presents the design of a bondwire antenna with detailed equations showing the derivation of the radiated power, radiation pattern, and the transmitter to receiver link-budget for a bondwire-antenna for short-range radio communications in the 6.5 GHz frequency range. The bondwire antenna is then used to design a high-gain, narrowband duplexer-less LNA/PA blocks for a transceiver with the LNA input and PA output automatically matched to the antenna. Besides the inductive bondwire antenna, the LNA and PA are designed to be inductor-less, thus saving the silicon chip area. The transceiver range is calculated to be about 2.27 m, ideal for applications such as 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 6.5 GHz are S21 of 15 dB for the LNA and 7 dB for the PA, NF of 5.7 dB for the LNA, S11 and S22 less than -10 dB, with 9.8 mW for TX and 14.6 mW for RX power consumption for 1.2 V supply.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
