Fabrication and modeling of an SP3T RF MEMS switch
Bibliographic record
Abstract
Most of the research effort on RF MEMS switches reported in the literature has been directed toward the development of single-pole-single-throw (SPST) switches. The SPST switch is a two-port device, which acts as a simple RF relay. In today's communication systems, switches are typically used in the form of switch matrices. The use of multiport switches as the basic building blocks can considerably simplify the integration problem of large switch matrices. In our knowledge, very limited work has been reported on integrated multiport MEMS switches. We present a novel integrated SP3T MEMS switch. RF simulation, along with circuit modeling, is used to design the switch. Three beams with narrow-width tips are integrated on top of a coplanar transmission line. The junction where the three beams interact is inherently a wide band junction, which makes it possible to design a wideband SP3T switch with 30 dB isolation up to 20 GHz. Theoretical and measured results demonstrate the validity of the proposed design. Even though the concept is demonstrated using flip-chip technology, the SP3T switch can potentially be realized by integrating the beams and the substrate on one chip.

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.
