STRIPLINE FILTERS WITH LUMPED CAPACITANCES G. Reiter ABSTRACT In the lecture, the arrangement and design procedure of stripline filter is out lined. The filter having lumped capacitive -sections as coupling elements and other parallel lumped capacitances connected to each other by very short transmission line sections.This construction can be applied for a filter with narrow relative bandwidth

THE DESIGN OF HIGH POWER 12 GHZ MICROWAVE SATELLITE S. Singer COMPONENTS SYSTEMS & G. Woods FOR USE IN BROADCAST V. O'Donovan, COMMUNICATIONS S. Kallianteris, ABSTRACT A number of broadcast satellites operating in the 12 GHz band are scheduled for launch in the next decade. This paper presents a status report on a long term program aimed at advancing the technology of microwave components

ELLIPTIC CHANNEL W. Hagele FUNCTION BRANCHING FILTERS NETWORKS FOR 11 GHZ The design of an 11 GHz channel branching filter which has to meet high stopband attenuation requirements demonstrates that elliptic-function filters are superior to conventional filter types as regards insertion loss and size. The conctruction of a 6-section filter with couplings between non-adjacent resonators is pres

SIMPLE ELLIPTIC-FUNCTION AND SOU-RIGID O. Kasuga, CABLES FILTERS MADE OF RECTANGULAR WAVEGUIDE T. Kyuzaki and R. Tamura ABffi'RACT A semi-rigid cable makes a conventional waveguide filter into an ellipticfunction filter. A four-resonator elliptic-function filter having a simple construction and a selectivity equivalent to that of a tenresonator Butterworth filter has been developed by addin

A WAVEGUIDE MULTIPLEXER WITH DUAL-MODE FILTERS FOR SATELLITE USE G. Pfitzenmaier x) ABSTRACT The paper treats the synthesis, optimization and practical realization of a 4 GHz waveguide multiplexer composed of a WR22Q straight waveguide manifold with one end shorted and dual TE111-mode Chebyshev bandpass filters arranged at intervals along the broad wall sides. The optimization process inc

. USE OF DIELECl'RIC MIcroPIDBES FOR ELECl'IDMAGNEl'ICFIELDS MEASUREMENT A. DEFICIS + ABSTRACI' Since 1971, our Research department is studying dielectric probes for measuring the penetration of electromagnetic waves in not-clearly defined media. These probes call for the following techoology : - dielectric light conductors a dielectric thermo-sensitive system - an electromagnetic waves abso

"A POCKET SIZED MONITOR OF DANGEROUS MICROWAVE POWER LEVELS" R.Agarwalt S.Hannaht* H. Hartnagelt J.T. Kennair*. ABSTRACT A miniature battery-operated microwave power monitor is described which operates across the threshold range of biologically dangerous power levels with approximately frequencyindependent characteristics up to about lOOGHz. CMOS circuitry causes an alarm signal to occu

MEASUREMENT OF TEMPERATURE AND MICROWAVE POWER USING LIQUID FIBER PROBES CRYSTAL/OPTIC T. C. Rozzell*, C. C. Johnson+ and O. P. Gandhi+ Abstract. Two electro-optical probes have been developed which make possible the measurement of microwave power density inside biological specimens or phantoms and the continuous monitoring of temperature of the specimen during exposure to microwaves. Several

A SYSTEM FOR QUANTITATIVE CHRONIC EXPOSURE OF A POPULATION OF RODENTS TO UHF FIELDS Arthur W. Guy, Chung-Kwang Chou, and Richard H. Lovely* ABSTRACT A system has been developed for economically exposing a large portion of rodents on a long-term basis without disturbing their normal laboratory living patterns. The use of separate cells consisting of cylindrical waveguide excited with circula
