Designing and Constructing a TV Combiner Using Phase Line Method
نویسنده
چکیده
TV combiner is a device which can be used to transmit two or more TV or FM programs with different frequencies and power levels by a single wide band antenna simultaneously. One of the following three methods is usually used for its construction: 1-Star Point Filters, 2-Directional Coupler Filters and 3Phase Line Method. In this paper, using phase line method which is simpler compared to other mentioned methods, we have designed and constructed a sample two-way 200w TV combiner in UHF band. The constructed device has shown satisfactory performance in testing and measurements and also in real-world operation. Key-Words: TV Combiner, Directional Coupler, Phase Line, HPHFSS, UHF.

Experimental and Simulation Constructing of Phase Diagram and Quality Lines for a Lean Gas Condensate Reservoir Fluid
Constructing phase diagram and its subsequent quality lines for lean gas condensate reservoirs is always crucial and challenging topic in reservoir fluid studies. Due to small amounts of liquid drop-outs in lean gas condensates at reservoir conditions, full experimental tracking of phase diagram and its relevant quality lines is almost impossible for lean gas condensates.On the other hand, ...

Our aim in this research is to design a model for children TV education with a cognitive approach to environmental education. People are bombarded by information in the media age, and this subjection to various news has made the learning process hard. Especially because a part of this sort of education is done by these media. The public education whose addressees are the public is done by mass ...
متن کاملPhased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
متن کاملDesigning and Constructing an Optical System to measure Continuous and Cuffless Blood Pressure Using Two Pulse Signals
Introduction Blood pressure (BP) is one of the important vital signs that need to be monitored for personal healthcare. Arterial blood pressure is estimated from pulse transit time (PTT). This study uses two pulse sensors to get PTT. The aim of this study was to construct an optical system and to monitor blood pressure continuously and without cuff in people with different ages. Materials and M...
