The suppression of spurious in fifth overton crystal units
2013 21st Telecommunications Forum Telfor (TELFOR), 2013Paper describes a new technological process of suppression of spurious in fifth overtone crystal units (CU) AT cut type. The development of new crystal filter is based on micro-miniature quartz crystal units, because of the reduced size of new devices in telecommunications.

Balanced bandpass filter with spurious mode suppression
Microwave and Optical Technology Letters, 2017ABSTRACTThis article presents a new and simple design approach for the balanced bandpass filter (BPF) with spurious mode suppression using half‐wavelength resonators. The second harmonic of the resonator, acting as the lowest‐frequency common‐mode (CM) noise, is suppressed by using a new differential feeding scheme. Furthermore, an electrically coupled

Suppression of Spurious SAW Signals
IEEE 1986 Ultrasonics Symposium, 19861.0 ABSTRACT Digital Radio applications of SAW require that individual spurious signals in the time domain be suppressed by about 60 dB. The first concept to be discussed involves a silicon thin film absorber with a tapered transition between the transducer and the free substrate region.

Simple Suppression of Spurious Peaks in TROSY Experiments
Journal of Magnetic Resonance, 2000In (1)H-(15)N TROSY experiments of proteins and nucleic acids, where the second coherence transfer delay time tau' has been fixed as 5.6 ms, 1/(2(1)J(NH)), in order to achieve complete spin-state selection, spurious negative peaks are observed along the (15)N axes. These peaks are often annoyingly large, especially for nucleic acids.

Oscillator design for suppressing spurious signals
IEEE Microwave Magazine, 2007This article has shed some light upon typical problems of the oscillator design. A number of additional signals can be excited by the oscillator's active kernel due to parasitic effects. These interfere with the projected oscillation frequency or with its harmonics and produce a number of disturbing spurious signals.

Microstrip filter with suppression of spurious-bands
2011 10th International Conference on Telecommunication in Modern Satellite Cable and Broadcasting Services (TELSIKS), 2011A method of the suppression of spurious bands in the amplitude-frequency response of the filters containing micro-strip resonators with the coupling performed by lumped inductances has been proposed. It has been suggested to eliminate spurious bandpass in the amplitude-frequency response of the microstrip filters.

High spurious suppression 60GHz transceiver
2015 Asia-Pacific Microwave Conference (APMC), 2015This paper proposed a high frequency spurious suppression 60GHz transceiver, which is composed by single module. It works in the 59–64GHz RF frequency with two 2.16GHz bandwidth IF communication channels in the 8.64GHz. The cavity band pass filters are added in the output of the TX and the LO link to realize the high sideband reject and low spurious ...
