Book excerpt: "Lumped element directional couplers are desirable at frequencies below the VHF range because they eliminate the large physical size necessary for the distributed element directional couplers. The purpose of this work is to describe the theory and design of such low frequency lumped element directional couplers. A model for the coupler is developed and the equations which describe it are derived. Scattering matrices for one and two section couplers are obtained. Computer solutions for three section couplers are presented. Experimental results for one, two, and three section couplers are presented and comparison with theory are made. Comparisons of theoretical and experimental work show that lumped element couplers are useful at low frequencies"--Abstract, leaf ii.

Download or read book Broad-Band Lumped-Element Directional Coupler written by Cletus A. Hoer. This book was released on 1972. Available in PDF, EPUB and Kindle. Book excerpt: The patent describes a broad-band lumped element directional coupler for measuring either the forward or reflected power in a coaxial transmission line. A resistive voltage divider is coupled to the center conductor of a transmission line with a capacitor to keep the phase of the voltage sampling circuit equal to the phase of the current sampling circuit. Capacitors shunting the resistors make the voltage ratio of the resistive voltage divider independent of frequency over a large frequency range. Directivity greater than 50 dB is achieved over a large frequency range for coupling ratios of 30, 40 and 50 dB.

Book Synopsis Practical Filters and Couplers by : Noble Publishing Corporation

Download or read book Practical Filters and Couplers written by Noble Publishing Corporation. This book was released on 2001. Available in PDF, EPUB and Kindle. Book excerpt: Annotation A collection of 16 articles compiled from previously published magazine articles. The articles were selected based on their meeting one or more of three criteria: reviewing important techniques, solving practical problems, or presenting original ideas. Among the specific articles within the broader field of filters and couplers are discussions of matching double-tuned LC filters, microwave multiplexers using complementary filters, RF capacitive-coupled filters, and a new approach to broadband transmission line hybrid design.
