impedance matching

n.
The use of electric circuits, transmission lines, and other devices to make the impedance of a load equal to the internal impedance of the source of power, thereby making possible the most efficient transfer of power.

As mentioned in part 1, to ensure a reflection-free signal, high-speed nets require impedance matching. This means the driver (output resistance), transmission line and receiver must show as little as possible (and ideally no) impedance difference values.
On-chip antenna arrays at millimeter-waves will need active integrated antennas to compensate for the path losses at such high frequencies, they say, They cover impedance matching methods, amplifier design, antenna fundamentals, active integrated antennas, and a co-design approach.
It offers advanced functionality to maximise energy yield and peak string level AC/DC power using impedance matching technology.
While most people tend to focus on design and ergonomics when buying headphones, Sennheiser Asia Senior Product Manager Kuan Wee Hong emphasized that impedance matching is one important thing to consider.
Various performance metrics are considered in the design of an LNA, which usually include power gain (G), NF, linearity, stability, impedance matching and power dissipation ([P.sub.diss]).
Although the importance of the impedance matching and cavity tuning has been already found and discussed in medicine for microwave exposure to biological tissue [12] (at, obviously, a low temperature), those aspects are rarely evoked in hightemperature microwave processes.
However, viewing this limitation as an impedance matching problem for conventional antenna elements, an early approach is to locate a thin, high-permittivity dielectric sheet at some distance above a waveguide array [10].
Typical circuit applications include impedance matching, bypass, feedback, tuning, coupling and DC blocking.
* Efficiencies of 65 to 70 percent are typical and the solution exhibits excellent impedance matching over the frequency bands
The impedance matching method on the load side can simultaneously realize the compensation of the frequency splitting phenomenon and the control of the power distribution.
Moreover, the ambitious objectives of this project included achieving a real breakthrough in vibration control technologies creating an absolutely new kind of mechanical impedance matching device as a key tool for enhancing the effectiveness of other vibration control elements.
