Digital Fundamentals: The meaning of the term "digital" is fundamental to an understanding of the benefits of digital technology. Digital Fundamentals data must be compared with analog data in order…
Types of Optoelectronic Devices: Although light-emitting diodes and photodiodes are not quantum-mechanical devices in the Types of Optoelectronic Devices, they are semiconductor devices closely associated with lasers. It is most…
Cavity Magnetron Working: The Cavity Magnetron Working, which will be referred to as the magnetron, is a diode, usually of cylindrical construction. It employs a radial electric field, an axial…
Reflex Klystron Oscillator: It is possible to produce oscillations in a klystron device which has only one cavity, through which electrons pass twice. This is the Reflex Klystron Oscillator, which…
Antenna Coupling: Antenna Coupling : Low and medium frequency antennas are the ones least likely to be of resonant effective height and are therefore the least likely to have purely…
Choke Balun: A Choke Balun, or balance-to-unbalance transformer, is a circuit element used to connect a balanced line to an unbalanced line or antenna. Or, as is perhaps a little…
Double Stub Matching: If a transmission-line matching device is to be useful in a range of different matching situations, it must have as many variable parameters, or degrees of freedom,…
