RG-58. RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System. There are several versions covering the differences in core ...
SMA ( SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. The connector has a 50 Ω impedance. [ 1] SMA was originally designed for use from DC (0 Hz) to 12 GHz, however this has been extended over time and ...
Wilkinson power divider. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports. The Wilkinson design can also be used as a power combiner because it is made up of ...

Link budget. A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver. It is an equation giving the received power from the transmitter ...
Design. Color-coded PS/2 connection ports (purple for keyboards and green for mice) on the rear of a personal computer. An S-video connector: because this is a female connector, Pin 1 is at lower right. Mini-DIN connectors are 9.5 millimetres ( ⁄8 in) in diameter and come in seven patterns, with the number of pins from three to nine.
Cable. Coaxial. Passband. Typically 0–4 GHz. The BNC connector (initialism of "Bayonet Neill–Concelman") is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It is designed to maintain the same characteristic impedance of the cable, with 50 ohm and 75 ohm types being made. It is usually applied for video ...
Dielectric loss. In electrical engineering, dielectric loss quantifies a dielectric material 's inherent dissipation of electromagnetic energy (e.g. heat). [ 1] It can be parameterized in terms of either the loss angle δ or the corresponding loss tangent tan (δ). Both refer to the phasor in the complex plane whose real and imaginary parts are ...
