matched impedance

[′macht im′pēd·əns]
(electricity)
An impedance of a load which is equal to the impedance of a generator, so that maximum power is delivered to the load.

Cannon's Quadrax Contact is designed as a Size 8 contact assembly installed in a clocked Size 8 contact cavity insert and contains four matched impedance signal contacts within a shielded Size 8 body.
An example of the real-life impact of matched impedance is shown in FIGURE 6, where the switching behavior of a DDR3 data signal (point-to-point, the receiver only) is shown and where the memory vendor demanded an impedance value of 50[OMEGA].
Figure 5 shows a block diagram of the matched impedance measurement setup.
Notably, when one adds an extra structure to the original antenna, it will break the already matched impedance at some places over the entire band.
Low capacitance and matched impedance cable capabilities extend the life of the motor, reduces corona discharge and magnitude of standing waves while increasing the efficiency of power conversion.
Boards up to 16 layers, with or without blind and buried vias, and controlled and matched impedance, can be designed and priced using an automated RFQ process.
In Figures 6 and 7, we compare the statistics of the optimal receiver impedance to the statistics of the matched impedance, that is, the impedance that is designed to fulfil the power matching conditions.
The multi-channel devices also feature a flow-through design package that allows for matched impedance of PCB trace routing.
Because anechoic chambers provide a matched impedance termination, the internal field distribution depends largely upon the antenna characteristics and is predictable.
The CM1234 eliminates the need for these measures, providing matched impedance with no external compensation or components required.
The Hypertac contacts improve the performance of the PC/104 platform by providing immunity to shock and vibration fretting and allowing for matched impedance and better signal integrity.
Design engineers require a backplane connector that facilitates high-signal density at high speeds while exhibiting matched impedance, low insertion loss, and low crosstalk.
