A CONVOLUTION-BASED SAMPLE-BALANCE TECHNIQUE FOR THE ANALYSIS OF NONLINEAR MICROWAVE CIRCUITS
A CONVOLUTION-BASED MICROWAVE CIRCUITS SAMPLE-BALANCE TECHNIQUE FOR THE ANALYSIS OF NONLINEAR P.J.C. Rodrigues, M.J. Howes, and J.R. Richardson* ABSTRACT A technique circuits Balance easier Transforms nonlinear of with equations. examples is for Techniques implementation (DFTs). block-SOR Stability of its finding (HBTs) and The method application. the are does technique is conditions u
KA BAND INTEGRATED DUAL FREQUENCY LO SUBSYSTEM
KA BAND INTEGRATED DUAL FREQUENCY LO SUBSYSTEM G Galambos*, ABSTRACT In the paper an integrated dual fequency LO subsystem will be presented that provides LO signals for a converter system that downconverts signals in the 18 - 40 GHz range (subranges 18 - 26;26 - 34;34 - 40 GHz) into the 4 - 8 GHz band (1). The LO frequencies for these conversions are 26 GHz, 30 GHz, and 34 GHz. One LO subsystem g

38-GHz BAND HIGH-POWER MMIC AMPLIFIER DESIGN USING IMPROVED LOAD-PULL METHOD
38-GHz BAND HIGH-POWER MMIC AMPLIFIER DESIGN USING IMPROVED LOAD-PULL METHOD Kazuo Nagatomo*, Shoichi Koike*, Masafumi Shigaki*, Naofumi Okubo*,Hidenori Takahashi**, and Tetsuji Nakatani** ABSTRACT To facilitate accurate amplifier design, the large-signal impedance of a GaAs FET with a O.25-µm-long gate was measured using an improved load-pull method. A new MMIC transformer was used in the mea
60 GHz DOWN CONVERTERS FOR SATELLITE LOW NOISE RECEIVERS
60 GHz DOWN CORVERTERS M. Piloni, ABSTRACT FOR SATELLITE LCM NOISE RECEIVERS G. Carpentiere * Since recent years, millimeter waves (MMW) are finding an increasing role in satellite communication systems. Concerning commercial application inter-orbit and inter-satellite communication at MMW, around 60 GHz and medium data rates, are very attractive because of their intrinsic immunity versus ear
MICROWAVE HIGH-POWER GaAs FET AMPLIFIERS
MICROWAVE HIGH-POWER Y. Mitsui* ABSTRACT GaAs FET AMPLIFIERS Solid-state power amplifiers(SSPAs) have been significantly improving in the past years and gradually replacing travelling wave tube amplifiers (TWT As) in the area of microwave and mm-wave communicatIon systems such as terrestrial communications equipment and satellite transponders. This paper surveys the recent research and developme

A NEW CLASS OF SCANNABLE MILLIMETER- WAVE ANTENNAS
A NEW CLASS OF SCANNABLE MILLlME'IER- WAVE ANTENNAS Arthur A. Oliner* ABSTRACT The complexity usually associated with scanning arrays at millimeter wavelengths produces fabrication difficulties, so that alternative methods are needed that employ simpler structures. This paper describes such an alternative scanning approach, and presents a group of new and simpler radiating structures suitable
THE APPLICATION OF LIGHTWAVE TECHNOLOGY TO MICROWAVES
THE APPLICATION MICROWAVES P.R. Herczfeld* OF LIGHTWAVE TECHNOLOGY TO ABSIR.Acr This paper concerns with the application of lightwave technology to microwave systems. In particular, the performance of fiberoptic links and their use in phased array antenna feeds and recirculating memory loops is discussed.
