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
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  (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 .
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.
