Microwave Noise Modeling for AlGaAs/InGaAs/GaAs PHEMTs

Analytical expressions for the noise parameters of microwave pseudomorphic high electron mobility transistors (PHEMT) are presented in this article. These expressions are derived from an accurate small-signal and noise equivalent circuit model, which t...
Pseudomorphic high electron mobility transistors (PHEMT) have shown excellent microwave and noise performance and are very attractive for millimeter-wave and optoelectronic applications. The complete characterization of these devices, in terms of noise and scattering parameters, is necessary for computer-aided design (CAD) of monolithic microwave integrated circuits (MMIC) or optoelectronic...

Software Analysis that Goes Far Beyond Electromagnetics

Analysis performed with traditional electromagnetic-field software might give a good sense of the operation of a microwave component from the perspective of pure electromagnetics under ideal conditions. Real-world operating conditions are not ideal, however, and the physical phenomena that affect a component’s performance often go beyond electromagnetics alone—effects from...
