Also, the spurious response
occurs far beyond twice the resonant frequency of the resonators, and the out-of-band rejection has been improved.
Frequency splash could either be a selectivity issue (depending on how narrowly-designed the band width is for each frequency) or another issue called spurious response
, which is the receiver's ability to reject harmonics.
Huang, 2007) have designed the triple EBG structures for a band stop filter, but there was a spurious response
and passband ripple in their performances.
10, the spurious response
around 9[f.sub.0] is suppressed after the L slot lines added.
It can control spurious response
by changing impedance ratio ([W.sub.in]/[W.sub.out]) of the nested SRR unit cells.
The unique design of the piezoelectric seismic system ensures that the units have no discernible spurious response
to mounting torque, body strains, cable vibration, cable whip, pressure variations, and most heat transients.
Keeping the spurious response
of a radio receiver down to a minimum is a major problem, particularly in the presence of strong signals to which the receiver is not tuned.
The jitter is <1 ps, phase noise <-80 dBc/Hz (100 Hz offset) at 622.08 MHz, and spurious response
It is summarized that this presented filter has the best suppression of spurious response
in LF band, high miniaturization level and reasonably low passband IL.
Therefore, the design of DBBSF with individually controlled stopbands and improved spurious response
Table 1 compares the sizes and harmonics characteristics of the proposed resonator of other published works with simultaneous size reduction and spurious response
suppression in reference.
6, the asymmetric open-stubs and rectangular micro-strips are introduced to generate transmission zeros around 3[f.sub.0] and 5[f.sub.0] ([f.sub.0] is 2.43GHz), respectively, while L slot lines can give a great suppression to the spurious response
around 7[f.sub.0], 9[f.sub.0] and 11[f.sub.0].
