In this paper, a switchable bandstop to allpass filter using cascaded transmission line SIW resonators is proposed. The performed by the discrete PIN diodes. Therefore, it can be used for rejecting any unwanted frequencies in communication systems. proposed design operated K-band and targeted millimeter wave front end system 5G telecommunication. Two designs with different orientation (design A...

the telecom services have been recognized the world-over as an important tool for socioeconomic development for a nation and hence telecom infrastructure is treated as a crucial factor to realize the socio-economic objectives in india. accordingly, the department of telecom has been formulating developmental policies for the accelerated growth of the telecommunication services.  bsnl is a wholl...

We implement a Synchronous Dataflow (SDF) model for the discretized data transmission in Very High-Speed Digital Subscriber Line (VDSL) using Agilent Advanced Design System (ADS) electronic design automation software. Our ADS implementation will enable designers to simulate and optimize different VDSL transceiver designs. The filters used at the VDSL receiver and the bit allocations for sub-cha...

ITU-T G.9904 standard, also known as PoweRline Intelligent Metering Evolution (PRIME), is a Power Line Communications standard for advanced metering, grid control and asset monitoring defined by the International Telecommunication Union (ITU). In this paper, an analysis about how different characteristics of the communication channel and types of noise might affect the system performance is car...

We design an ultracompact optical isolator with normal incident geometry that operates with a bandwidth that is substantial for a device of this size. For operation in a telecommunication wavelength of 1.55 μm, the thickness of the device is less than 1 μm and the device supports an operating bandwidth of 400 GHz over which the minimum contrast ratio exceeds 25 dB. Our design utilizes guided re...

Millimeter waves are increasingly used in modern telecommunication systems for wireless data transmission. However, higher path loss, especially caused by non-line-of-sight scenarios, remains challenging. The design of an electrically controllable reflector the millimeter-wave range is elaborated and presented this manuscript. was based on distributed ferroelectric ceramic elements could be a f...
