Using a C++ based simulation framework and automatic differentiation techniques for advanced non-linear modelling of microwave active devices Peter Feldmann, Robert Melville*, Vicentiu Cojocaru and Thomas Brazil** Abstract In this paper we describe the use of a novel, flexible, and highly modular simulation environment called Sframe, for microwave device modelling and circuit simulation. The sof

Large-signal performance of measurementbased diode models for nonlinear circuit simulation: a . comparison Marco Pirola*, David E Root** and Giovanni Ghlonet* Abstract This paper presents a new, extensive investigation of the large-signal behaviour of two measurement based mathematical diode models. A physics-based dynamic nonlinear model of a p+n diode, and the Nonlinear Integral Model[1]derived

A millimeter-wave wideband balanced amplifier using multilayer MMIC directional couplers Toshlkuulmaok8*, Bellchl Banba**, Nobu.kllmal* Abstract This paper describes a millimeter-wavewideband balanced amplifier using novel multilayer MMIC directionalcouplers. The 3 dB-couplers designed fora center frequency of 50 GHz show coupling losses of 3.9 dB ± 0.3 dB.The balanced amplifierfabricated in a 1.

A 60-GHz HEMT-based MMIC directdetection receiver for application in non-contact ID card systems Katsujl Ono*, Tamio 8allO*, Norlo Hidaka*, Yoll Ohashl**, and Yoshio Aoki*** Abstract We report a 60-GHz HEMT-based MMIC directdetection receiver incorporated with an input and an output RF amplifier. This MMIC uses an InGaP/lnGaAs/ GaAs pseudomorphic HEMT structure for a noncontact ID card applicatio

A 45.50GHz Monolithic Integrated HFET/MSM OEIC Receiver Hiroshi Kawamura*, Eql Suematau**, and Nobuakllmai* 1. Abstract A monolithic HFET/MSM OEIC receiver for optical signals in the frequency range of 45 GHz and 50 GHz is presented. This is the first OEIC receiver that operates in the millimeter-wave band as far as the authors know. In the OEIC receiver, an MSM photodetector and a 3-stage trans

Synthesis of modular multiplexers employing interconnected Y-junctions manifolds Antonio Morini and Tullio Rozzi Dipartimento di Elettronica ed Automatica, Universita di Ancona, Via Breece Bianche, 60131 Ancona, Italy Abstract This work describes a class of modular multiplexers, obtained from a manifold realized by connecting Y Junctions. The properties of the Y-junction afford good performance wh
