Abstract

An ultra-wide stopband bandpass filter (BPF) using second-order M-type circuit is proposed by virtue of glass-based integrated passive device (IPD) technology. The second-order M-type circuit is composed of two first-order M-type circuits in series. The first-order M-type circuit consists of a low-pass filter (LPF) and a high-pass filter (HPF), each of which can generate one transmission zero. The second-order M-type circuit can generate two transmission zeros in the low frequency band and another two transmission zeros in the high frequency band, which can achieve high rejection in the upper ultra-wide stopband. The proposed BPF covering 3.3–4.2 GHz is fabricated with a compact size of 1.0 mm × 1.0 mm × 0.3 mm on glass-based IPD technology. According to the measurements, the fabricated BPF can achieve a minimum in-band insertion loss less than 1.4 dB, a return loss better than 15.6 dB, and more than 20 dB ultra-wide stopband rejection from 5.81 to 43.5 GHz. Compared to the previous designs, the proposed BPF shows the superior advantages of compact size and ultra-wide stopband.

期刊介绍： Prediction through modelling forms the basis of engineering design. The computational power at the fingertips of the professional engineer is increasing enormously and techniques for computer simulation are changing rapidly. Engineers need models which relate to their design area and which are adaptable to new design concepts. They also need efficient and friendly ways of presenting, viewing and transmitting the data associated with their models. The International Journal of Numerical Modelling: Electronic Networks, Devices and Fields provides a communication vehicle for numerical modelling methods and data preparation methods associated with electrical and electronic circuits and fields. It concentrates on numerical modelling rather than abstract numerical mathematics. Contributions on numerical modelling will cover the entire subject of electrical and electronic engineering. They will range from electrical distribution networks to integrated circuits on VLSI design, and from static electric and magnetic fields through microwaves to optical design. They will also include the use of electrical networks as a modelling medium.
