A hairpin bandpass filter with compact feeder structure is proposed for terahertz (THz) applications by using the model of odd-even propagation mode. By employing the three-dimensional integrated through-silicon via (TSV) technology, the proposed filter exhibits an ultra-compact size of only 0.24 × 0.028 mm 2 (1.38 × 0.16 λg 2 ). The model of the proposed filter is established and optimized with the HFSS tool based on finite element method. The results of S-parameters reveal that the proposed filter with center frequency at 0.5 THz, exhibits a bandwidth of 0.08 THz with insertion loss of 1.5 dB and reflection loss over 13.4 dB in the passband.INDEX TERMS hairpin bandpass filter, terahertz applications, odd-even model, through-silicon via (TSV).

Band pass filter comparison of Hairpin line and square open-loop resonator method for digital TV community

et al. 2021

The selection of the right filter design method is a very important first step for a radio frequency engineer. This paper presents the comparison of two methods of band pass filter design using hairpin-line and square open-loop resonator. Both methods were applied to obtain filter designs that can work for broadcasting system in digital television community. Band pass filter was simulated using design software and fabricated using epoxy FR-4 substrate. The results of simulation and measurement shown return loss value at 27.3 dB for hairpin line band pass filter and 25.901 for square open-loop resonator band pass filter. Voltage standing wave ratio parameter values were 1.09 and 1.1067 for hairpin line and square open-loop band pass filter respectively. The insertion loss values for the Hairpin line band pass filter and square open-loop band pass filter were 0.9692 and near 0 dB, respectively. Fractional bandwidth, for hairpin line band pass filter, was 6.7% while for square open-loop band pass filter was 4.8%. Regarding the size, the dimension of square open-loop resonator was approximately five times larger than hairpin-line band pass filter. Based on the advantages of the hairpin line method, we recommend that researchers choose the filter for digital TV broadcasting.

The world of Wireless Technology has been improving consistently due to its high speed and reliability. Some of the demands that need to be fulfilled include larger network capacity, improved data rates and so on. This paper focuses on the design and simulation of the Transmitter, which is a key component in an RF Transceiver Module. It is built by cascading an Up Conversion Mixer, a Bandpass Filter and a Power Amplifier as its most fundamental units. The Cadence Virtuoso Tool was used to construct this Transmitter block in 180nm node technology. The IF signal to the Mixer is 100 MHz and the LO signal is 2.3GHz. The 2.4GHz amplified RF output is taken from the Power Amplifier. A 1dB compression point of -25.91 dBm and an IIP3 of 10.14 dBm is observed for the proposed design. Future work involves testing its integrity with an RF Receiver module that has appropriate modulation schemes in place and converting it into a physical layout-based IC.
