loaded Q

[′lōd·əd kyü]

(electricity)

The Q factor of an impedance which is connected or coupled under working conditions. Also known as working Q.

(electromagnetism)

The Q factor of a specific mode of resonance of a microwave tube or resonant cavity when there is external coupling to that mode.

Note the very narrow bandwidth of the resonance, a result of high loaded Q. The contact pad and ground geometry of the product is ideally suited to precision measurements of resonant frequency and input impedance using coplanar RF probes.

Ceramic resonator designs can be tailored to adjust the loaded Q and input impedance of the device over a broad range.

In VCOs intended to provide a fixed frequency reference, as in SONET and many communications receivers, maximum circuit loaded Qs are limited by several tolerance elements: frequency set-on accuracy, frequency stability over operating temperature range and aging effects.
