Design of a Metamaterial Bandpass Filter Using the ZOR of a Modified Circular Mushroom Structure

In this article, the design of a new bandpass filter, based on a modified circular mushroom metamaterial structure, is proposed. Half circular mushroom cells are used as the zero-order resonators (ZOR), and an intermediate gap is used to capacitively c...
Wireless communication gadget users nowadays tend to pursue more convenience, such as multi-functions and higher mobility. The former results in a multi-band service oriented device; the latter drives the development of reduced size equipment. Thus, the roles and expectations of RF components are becoming more challenging. In particular, quality...

A HEMT Large-signal Model with Improved Transconductance and Gate Capacitance Peaking Characteristics

In this article, an improved large-signal device model of HEMTs is presented, amenable for use in commercial nonlinear simulators. The proposed model includes independent modeling equations to control the peaking and compression behaviors of the HEMT t...
The availability of general-purpose harmonic-balance and Volterra-Series simulators has generated a need for accurate nonlinear models of III-V field effect transistors (FET). 1 Due to the heterostructure complexity of HEMTs and the associated physical characteristics, they are most appropriately modeled based on a semi-empirical approach with parameters extracted from...
