Based on the signal interference concept, the selectivity of a BPF using composite right/left handed transmission line (CRLH TL) unit cell is significantly improved. Thus, by employing a single coupled line section and CRLH TL unit cell in the feedback, a bandpass filter with high selectivity, multiple transmission zeros (TZs) within the upper stopband and low insertion loss can be realized. The simulation results show that the proposed BPF has a fractional bandwidth of 8% centred at 2.4 GHz with high roll-off rate of 300 dB/GHz.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"91 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115364775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The circuit is implemented by using a three-branch bandpass N-path switched-capacitor filter architecture. A selective pre-filter (FM) is implemented at the input of the receiver that allows an attenuation higher than 10 dB for the adjacent channel interferer located 23-MHz away from the center frequency of the considered channel. Two other parallel-type branches of N-path bandpass filters (FA1 and FA2) with downward and upward frequency shifting are used. The outputs of the pre-filter and the two other bandpass filters are subtracted to create two close-to-passband transmission zeros that enable to achieve high selectivity in the overall filtering transfer function. The channelized bandpass filter can be frequency tuned from 0.2 GHz to 1 GHz. The gain, NF, and channel bandwidth of the filter at 500 MHz are around 20 dB, 4.7 dB, and 5 MHz, respectively. The circuit has been designed with 0.25 µm BiCMOS process of NXP technology using Cadence SpectreRF circuit simulator.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116787850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multilayer laminate consists of the glass and carbon based fabrics along with lossy dielectric fillers in the epoxy medium. The individual laminates have been fabricated using vaccum bagging technology and their constitutive electromagnetic properties e.g. dielectric constant and loss tangent have been evaluated using the quasi optical free space measurement system (QOFMS) in the W band (75–110 GHz) frequency region. Based on the simulated results, optimized monolithic configuration of individual laminates have been fabricated and tested for the electromagnetic absorption using QOFMS. The experimental result shows minimum 10 dB reflection loss (90% electromagnetic absorption) across the entire frequency region.

A dual-mode square loop resonator and three varactor diodes are used to achieve the tunability operation. The dual-mode square loop resonator is coupled to a straight transmission line that connects input and output ports. One of the varactors is used as a perturbation element on the symmetrical axis of the resonator and even mode resonance frequency can be tuned by changing the capacitance of its. Remaining two varactors are located at the lateral arms of the resonator as reference elements and they have task on the tunability of the odd mode resonance frequency. Depending on the capacitance changes of the varactors, both of center frequency and bandwidth of the stopband can be tuned.

A single-piece prototype waveguide design is used for testing the plating process, and a discussion is provided on minimizing printing process variables such as polymerization shrinkage and undesirable geometric tolerance variance. Measurement results of plated WR-10 1-inch waveguide sections show reflection coefficients of less than −21dB and an insertion loss of less than 0.53dB, which are comparable to similar studies using specialized plating and split-block designs. Furthermore, this approach shows great potential in providing an affordable passive microwave component rapid prototyping solution for research environments.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129648857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
