Web17 Dec 2010 · To increase the upper stop-band width of a superconducting spiral filter, a spurious response was suppressed using additional, deliberately lossy, resonators. Their fundamental resonant frequency is equal to the spurious resonance of the main spirals, and their bandwidth is limited, so they introduce very little loss in the main pass band, and … WebThe Mixer Spurious chart is a graphical representation of wanted and unwanted (spurious) mixing products in-band and out-of-band. Its main use is found in conjunction with mixers, however, it can be applied to all kinds …

In radio communication, a spurious emission is any component of a radiated radio frequency signal the complete suppression of which would not impair the integrity of the modulation type or the information being transmitted. A radiated signal outside of a transmitter's assigned channel is an example of a spurious emission. Spurious emissions can include harmonic emissions, intermodulation products and frequency conversion products.

WebSuch filters suffer from the presence of spurious pass-bands (responses) [1] corresponding to propagation of higher order waveguide modes of TE N0 origin (where N>1).
