Chloroplast analysis of Zelkova schneideriana (Ulmaceae): genetic diversity, population structure, and conservation implications.
TL;DR: A phylogeographical study of two chloroplast regions in several Chinese Z. schneideriana populations, in order to examine the genetic diversity, population structure, and evolutionary history of the species.
Small-signal modeling of GaN HEMT switch with a new intrinsic elements extraction method
TL;DR: In this article, a novel and accurate method was proposed to extract the intrinsic elements of the GaN high-electron-mobility transistor (HEMT) switch, which was verified by comparing the simulated S-parameters with the measured data over the 5-40 GHz frequency range.

X-band 5-bit MMIC phase shifter with GaN HEMT technology
TL;DR: In this paper, the design approach and performance of a 5-bit digital phase shifter implemented with 0.25-μm-GaN HEMT technology for X-band phased arrays are described.

Isolation and characterization of polymorphic microsatellite loci from Zelkova schneideriana Hand.-Mazz.
TL;DR: An improved technique for isolating codominant compound microsatellite markers was used to develop simple sequence repeat markers for Z. schneideriana, which will be very important for future research related to the genetic diversity, population structure, patterns of gene flow, and mating system of this species.
An X-band 22.5°/45° digital phase shifter based on switched filter networks
TL;DR: In this paper, the phase shift error, insertion loss and return loss in the X-band (40%), which can be employed into the wide bandwidth multi-bit digital phase shifter.
