insertion loss

[in′sər·shən ‚lȯs]
(electronics)
The loss in load power due to the insertion of a component or device at some point in a transmission system; generally expressed as the ratio in decibels of the power received at the load before insertion of the apparatus, to the power received at the load after insertion.

insertion loss

The amount of loss attributed to a particular device being used in (inserted into) the system. For example, a circuit added to filter out unwanted frequencies may reduce the output current by some amount. See injection loss.

Insertion loss has been preferred because all measurements are made at the outlet of the duct.
Some say trace width isn't a big deal when it comes to loss, but here we learned wider trace widths can be a great lever for reducing insertion loss. Megtron 6 (G), a relatively expensive low-loss dielectric, under-represents the range of dielectric-loss possibilities among the various laminates on the market.
It's important to minimize insertion loss over the frequency range of interest: even though the post-connector signal can be amplified, too large an insertion loss may result in an unacceptable degradation of system performance.
Transmission and insertion loss are the two metrics most commonly used to evaluate the performance of a muffer system.
Storage OEM's internal serpentine SI TV - Tachyon had an insertion loss of 0.621 dB/in.
Insertion loss was determined by measuring the sound pressure in one-third octave bands in the receiving room with and without the plenum inserted into the duct connecting source and receiving rooms.
Conductor loss is based on many variables and is often the culprit of unexpected increases in insertion loss when troubleshooting RF circuit performance.

Figures 2 to 3 show the average value and the standard deviation from the average value of the insertion loss at the three frequency bands for horizontal and vertical polarization.
Comparing these results with that of [9], it can be noticed that the insertion loss at the farthest points of our metallic door is almost the same of work [9].
In TDD system, a low insertion loss SPDT switch is needed in the transmit model in order to transmit power at a minimum loss from the PA (power amplifier) to the antenna and protect the sensitive receiver circuits from high power reflected signal from antenna.
These methods have a number of limitations, such as an increase in the size or the insertion loss of the device.
