Low dielectric losses and the applicability of highly conductive materials are making them desirable in production of high quality passive components, most often capacitors and inductors. These are the reasons that made this technology attractive for the circulator fabrication, and present the core of this paper. Bosma type of the circulator with Y-junction configuration is the topic of this work and is intended to use at the 5 GHz. Field analysis and the design of the circulator was adopted from Bosma in [3] and Wu in [4]. Theoretical analysis from these works predicts the values of geometrical parameters and the COMSOL simulation was made to confirm its validity. The fabrication process included standard LTCC production procedure consisting of dielectric and ferrite tape preparation, laser cutting, photolithographic screen stencil preparation, screen printing, lamination and, finally, co-firing. Fabricated samples were magnetically polarized and characterized. To maintain magnetic polarization of the produced circulator, small disk shaped neodymium magnets were placed on top and bottom of the ferrite discs. Measurements and characterization were performed on vector network analyzer in range of 4.5 - 8 GHz.","PeriodicalId":431569,"journal":{"name":"2015 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131542060","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 fabricated at the least spending with 0.5-μm GaAs PHEMT technology and standard plastic QFN package. Thanks to efficient design approaches, this compact packaged power amplifier MMIC (7.1mm2) demonstrates a measured linear gain averaging 30 dB across the full PtP Ku-band, and delivers more than +32 dBm CW power at 1-dB gain compression (P1dB), and +33 dBm output power in saturation (Psat). Typical measured OIP3 is greater than +41 dBm. To further reduce the cost and minimize component count in RF module, the PA MMIC integrates a temperature compensated on-chip power detector with 45-dB dynamic range for output power monitoring, together with on-chip EOS/ESD protections to ±400 V CDM for rugged and reliable operation. The overall PA performance, covering both the 13 and 15 GHz PtP bands with a single circuit, competes favorably well to other more advanced solutions reported in the literature or available on the market. Furthermore, the presented compact design considerations can be applied to greatly reduce manufacturing cost in other circuits and technologies (e.g. GaN).","PeriodicalId":431569,"journal":{"name":"2015 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983655","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}
