    This paper presents a CMOS cross-coupled film bulk acoustic resonator (FBAR) oscillator which was designed in class-C topology in order to improve phase noise and power consumption. The designed class-C FBAR oscillator shows lower phase noise with the same power consumption than that of a comparatively designed class-B FBAR oscillator. The efficient current generation in class-C leads to the impro... View full abstract»

The lines that are coupled to the ring are placed on the top layer while the ring is placed on the second layers to reduce the coupling gap. The centre frequencies of the two passbands are 2.5 GHz and 5.2 GHz. The dualban... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (612 KB) | HTML iconHTML

    A design of Substrate Integrated Waveguide (SIW) diplexer is proposed. The diplexer is formed using two SIW circular cavity resonators designed individually and combined through a T-junction. The circular cavity structure using TM010 mode is employed in the design of this diplexer.

    This paper examines the effect of loading a microwave cylindrical cavity with radially slotted dielectric rod. Although, methods for the computation of the resonant frequency of dielectric loaded cavity have been presented in the literatures, the effect of placing radial slots on axisymmetric dielectric load in relation to the cavity resonance has not been studied. The study was carried out using ... View full abstract»

    A rectangular shaped defective ground structure (DGS) is proposed to enhance the response of an existing design of a dual-band bandpass filter topology. In this paper, the filter design is based on parallel-coupled lines connected to transmission lines. The filter consists of characteristics impedances of the transmission line represented by Zr, even-mode, Zre and odd-mode, Zro. The variation of t... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1813 KB) | HTML iconHTML

    A second- and a third-order filters are presented based on the single-side-coupled ring resonator topology. A simple way to obtain the second-order bandpass response is proposed by adding a quarter-wavelength coupled line immediately at the coupled-line side of the resonator, which forms a half-wavelength resonator, hence an extra pole. Using the similar idea, an extra pole is obtained from a half... View full abstract»
