THE REFLECTIVE A FREQUENCY SENSITIVE ASW MULTI STRIP DEVICE FOR FILTER ARRAY AND CHANNEL BANK Michel FELDMANN and Jeannine HENAFF * ABSTRACT A frequency sensitive ASW structure is presented, operating by reflection of acoustic surface waves. Such a structure is of interest for frequency filters and filter banks. The response can be computed by scattering matrices leading to a good agreemen

CONVOLUTION IN A PULSE ~ BIASED ZnO-SIOZ-Si ~ SAW DEVICE ~ ~~ J. K. Elliott," R. L. Gunshor," R. F. Pierret," and K. L. Davis"" ABSTRACT A monolithic SAW device consisting of an rf sputtered ZnO film on a thermally oxidized silicon substrate has been shown to be useful for several signal processing and optical image scanning applications. The device efficiency and sensitivity can be vari

QUASI-OPTICAL MILLIMETER WAVEGUIDES AND COMPONENTS Raj Mittra ABSTRACT In this paper we review a number of quasi-optical waveguide structures and discuss their application to millimeter-wave integrated circuits. Some novel designs for dielectric waveguides and passive components using these waveguides are described. A summary of the results of theoretical and experimental studies of these waveg

ACOUSTIC SOME Jeannine SURFACE SIGNAL HENAFF WAVE AND CHARGE TRANSFER DEVICES IN PROCESSING * APPLICATIONS ABSTRACT Both acoustic surface wave and charge transfer devices technologies are now maturing. The present paper presents a survey of few analog applications restricted to civil communication systems. Actually, the input signal is delayed and weighted in the same way in both devices.

ACCURATE SCATTERING NETWORKS PARAMETER MEASUREMENTS ON NON-CONNECTABLE MICROWAVE R. A. Speciale, R. E. Grabowski, N. R. Franzen* ABSTRACT The development of an explicit and exact algorithm, computing the equivalent error representation for a network analyzer system, makes accurate measurements possible upon non-connectable microwave networks, embedded in complex transmission line environments

A NEW CALIBRATION MEASUREMENTS TECHNIQUE FOR AUTOMATED BROADBAND MICROWAVE Harry Cronson and Leon Susman ABSTRACT This paper presents new results in the area of precision microwave measurements using "six-port techniques". These techniques allow one to compute the complex ratio of two signals using power measurements alone. After proper calibration of the six-port network, the output of 4 s

A NEW PRINCIPLE LINEAR PHASE FOR MEASURING ELECTRICAL LENGTH AND DEVIATION FROM Hugo Vifian* ABSTRACT This paper presents a unique way to measure the equivalent electrical length of a network as well as its deviation from linear phase. The measurement technique used is based upon a variable length transmission line simulator, built into the IF-structure of a 1.3 GHz Network Analyzer, but can

A.M BOTTREAU and 70 GHz) APPLICATIONS. *, Cl MARZAT*and J MOREAU* ABSTRACT. - The determination of the complex 70 GHz (8 and 4 milimetre wavelengths) presents soon as it becomes necessary to study materials and having large loss tangents (tg ~ 1). Therefore, displacements of the permit

WIDEBAND MEASUREMENT OF MILLIMETER CIRCUITS FOR VARACTORS AND IMPATTS G. CACHIER"'", J. STEVANCE"', J.L. VATERKOWSKI"'1f , D.C. DEJAEGER'Ifr"" ABSTRACT We propose to measure the impedance of a millimeter - IMPATT circuit by using a modulated microwave signal source or a signal with two frequency components. The diode is biased below its breakdown voltage, and it is used both as a
