Characteristics of Single- and Multiple-Frequency Impedance Matching Networks
IEEE Transactions on Circuits and Systems II: Express Briefs, 2015The simplest network for matching a load resistance $R_{L}$ to a source resistance $R_{s} $ at a single frequency is analyzed to find an expression for the matching bandwidth with a specified tolerance on the reflection coefficient. The results are used to find the characteristics of dual- and triple-frequency impedance matching networks ...

Impedance Matching Networks Designed by Evolutionary Algorithms
2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019A key challenge to extend the operation of electronics nanodevices to mm-wave and THz frequencies is the large impedance mismatch among all components. Here we propose a methodology based on a genetic algorithm coupled to a 3D electromagnetic simulator for designing compact matching networks suitable for operation up to THz frequencies. Both narrow and

MEMS-based adaptive impedance matching network
SPIE Proceedings, 2003The architecture level design of an impedance matching network is presented for the global system for mobile communication radio frequency (GSM RF) power amplifier module used in a typical cellular handset. Designs for the low and high output impedance of the power amplifier and 50 Ω antenna impedance are considered.

Dynamic impedance matching network for RF energy harvesting systems
2014 IEEE RFID Technology and Applications Conference (RFID-TA), 2014In this paper, an RF energy harvesting system with an improved dynamic impedance matching network (DyIMN) is proposed. With this solution, the minimum RF input power required for circuit operation is −10 dBm, allowing a working distance of 1.5 m from an RF energy source of 30dBm.

A fast adaptive technique for impedance matching networks
Proceedings of 8th Mediterranean Electrotechnical Conference on Industrial Applications in Power Systems, Computer Science and Telecommunications (MELECON 96), 2002The present paper derives a fast recursive least squares algorithm for the design of impedance matching network to any complex termination. Starting from any non-zero initial values, and for any topology, the network components are derived iteratively in a manner that optimizes the network's insertion loss characteristics.

On the design of broadband elliptic impedance-matching networks
Journal of the Franklin Institute, 1976Abstract The paper provides practical means for selecting the optimum parameters for the design of a lossless coupling network that equalizes the parallel RC load to resistive generator and to achieve the n th-order elliptic transducer power-gain characteristic.

Practical considerations of impedance matching network design
Sixth International Conference on `HF Radio Systems and Techniques', 1994The paper investigates matchable range problems and Q-based design theory of Pi impedance matching networks. A method for determining impedance matching domains for any possible ranges of element values is presented. Boundary equations of matchable regions are formulated analytically and impedance realms are plotted with computers.

Very-Wide-Band Impedance-Matching Network
IRE Transactions on Component Parts, 1962A method is described for combining two transformers and supplementary network elements in a class of wideband impedance-matching networks whose over-all bandwidth in octaves is essentially the sum of those of the two component transformers. One transformer transmits the high-frequency portion of the required operating range and is relieved of the low ...
