Band gap, in solid-state physics, a range of energy levels within a given crystal that are impossible for an electron to possess. Generally, a material will have several band gaps throughout its band structure (the continuum of allowed and forbidden elec

An L-band gain and bandwidth tunable low-noise differential amplifier has been developed for the next generation reconfigurable wireless radios. It employs a varactor-tuned base bias circuit for tuning a lower band-edge frequency of the amplifier, a varactor-tuned collector bias circuit for tuning ...
An electronic circuit combines two or more individual wideband RF receivers or transceiver band circuits to produce a usable instantaneous bandwidth that is wider than the bandwidth of the individual band circuits. The electronic circuit overcomes the difficulties of combining bands to provide low signal...
In this paper, a 220 GHz broadband and high-power staggered double-vane traveling-wave tube has been designed and verified. Firstly, a planar double-beam staggered double-vane slow-wave structure is proposed. By using the double-mode operation schem
A wide-band band-pass filter (BPF) using coupled lines, rectangular stubs and Stepped-Impedance Resonators (SIRs) is presented in this paper. The proposed BPF operates over a large pass-band from 3.15 to 6.05 GHz covering 5G New Radio (NR) frequency
A quarter SR with an inner asterisk resonator (AR) is presented in34, where polarization angle insensitivity and absorption increase. In35, three different absorbers for single (T shape), dual (split-I shape), and multi-band (Split Jerusalem Cross) applications are presented. A shorted stub ...
SES has announced that the U.S. Federal Communications Commission (FCC) has validated the certification of SES’s Phase II accelerated C-band clearing and relocation activities. With this milestone and following the successful completion of its Phase I a
