Novel half mode substrate integrated waveguide power amplifier
Bibliographic record
Abstract
In this paper, a novel half mode substrate integrated waveguide (HMSIW) 10W power amplifier (PA) designed with HMSIW matching network (MN) is presented for the first time. The HMSIW-based matching network (MN) is designed with microstrip-to-HMSIW transition and an inductive metalized post in HMSIW. The impedance matching for the fundamental frequency 2.14 GHz is realized by moving the position of the inductive metalized post in the HMSIW. Both the input and output MNs are designed with the proposed HMSIW-based MN concept. One HMSIW-based 10W PA using GaN HEMT at 2.14 GHz is designed, fabricated, and measured. The proposed HMSIW-based PA can be easily connected with any microstrip or SIW-based circuit. Measured results show that the maximum power added efficiency (PAE) is 72.2 % with 40.7 dBm output power and the maximum gain is 20.1 dB. At the design frequency of 2.14 GHz, the size of the proposed HMSIW-based PA is comparable with other microstrip-based PAs.

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.
