Low Insertion‐Loss High Power X‐Band SPDT Transmit/Receive Switches in 250 nm GaN HEMT

Microwave and Optical Technology Letters, Volume 68, Issue 6, June 2026.
ABSTRACT We present three X‐band transmit/receive (T/R) switches utilizing single‐pole double‐throw (SPDT) structures in 250 nm GaN HEMT technology. The first T/R switch was designed to achieve low insertion loss by constructing the SPDT structure with a series λ/4 transmission line (T‐line) and meticulously selected two HEMT switches in parallel for ...

Unified regional modeling of GaN HEMTs with the 2DEG and DD formalism [PDF]

, 2012
This paper presents the unified regional modeling (URM) approach to developing a compact model (CM) for GaN-based high electron mobility transistors (HEMTs) based on the two-dimensional electron gas (2DEG) and drift-diffusion (DD) formalism.

Ternary Logic Transistors Using Multi‐Stacked 2D Electron Gas Channels in Ultrathin Oxide Heterostructures

Advanced Science
2D electron gas field‐effect transistors (2DEG‐FETs), employing 2DEG formed at an interface of ultrathin (≈6 nm) Al2O3/ZnO heterostructure as the active channel, exhibit outstanding drive current (≈215 µA), subthreshold swing (≈132 mV dec−1), and field ...

Optoelectronic transport through quantum Hall edge states

New Journal of Physics, 2015
We use GaAs-based quantum point contacts as mesoscopic detectors to locally analyze the flow of photogenerated electrons in a two-dimensional electron gas (2DEG) at perpendicular, quantizing magnetic fields.

Assessing D‐Squame as a Minimally Invasive Technique to Evaluate the Cutaneous Immune Response mRNA in a Dog Model of Canine Atopic Dermatitis

Veterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.
ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...
