Gyromagnetic nonlinear transmission lines are interesting new devices used for RF generation since they are all solid state, lightweight and compact, neither requiring vacuum nor thermionic filament as in electronic tubes. Experiments with these lines have demonstrated their successful operation at L and S bands, thereby enabling them for applications in UWB pulsed radars in space vehicles and defense...
Nonlinear transmission lines (NLTLs) are nonlinear LC ladder networks that can act as a nonlinear and dispersive medium, thus allowing the generation of soliton bursts. Several papers have been published indicating that NLTLs offer a new option for pulse shaping and RF generation. In this paper, we investigated the response of an NLTL driven by three different pulse shapes: a rectangular, a half sine,...
Nonlinear transmission lines (NLTLs) provides an ingenuous way of generating RF without using vacuum electron tubes. For high peak power, (MW) and frequency up to several hundreds of MHz dielectric or ferrite-segmented lines (a synchronous wave NLTL) have been used. Other configuration implemented with better frequency results (from 400 MHz up to 4 GHz in C-band) is a continuous ferrite loaded coaxial...
Nonlinear transmission lines have been used with great success in pulse sharpening for obtaining output fast pulse rise times in nanosecond and picosecond ranges. Nowadays recent research on this field has shown a great prospect for RF generation using these devices in aerospace application such as in ultra-wide band radar for communications, remote sensing and surveillance due to less attenuation...
As an alternative to replace microwave tubes used nowadays in compact space systems for satellites communications, this work examines the feasibility of using nonlinear transmission lines (NLTL) consisting of nonlinear components as varactor diodes, or capacitors modeled nonlinearly, as ideal circuits, without ohmic losses and real ones, with ohmic losses. All simulations were confirmed using equations...
Nowadays research on nonlinear element transmission lines (NLTLs) is an area of intense study for replacing electronic tubes in compact high power microwave devices in military applications, surveillance and monitoring systems, ultra-wide band radars, etc. Although, great success was achieved using based ferrite inductive element lines up to 1 GHz, attempts to operate at higher frequencies above 100...
