The adopted linearity metric is the highest inter-modulation distortion in a two-tone test with 20 MHz spacing. The simultaneous selection of optimum source and load terminations that provide the best trade-off among all of the requirements is described in detail, and the synthesis of the matching networks is then presented. A prototype is developed based on a 6 W packaged GaN device around 3.5 GHz, manufactured and measured. According to the measured results, the amplifier achieves output power higher than 38 dBm with associated gain higher than 12 dB and saturated power-added efficiency in excess of 73% in a single-tone test at 3.25 GHz, while providing a 33% power-added efficiency and -30 dBc inter-modulation distortion in the 20 MHz two-tone test.","PeriodicalId":207437,"journal":{"name":"2023 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129369207","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}

From the PA behavioral model, considering exclusively the nonlinear high-frequency (HF) memory effects, the linearization performance is evaluated. The behavioral model is modified to artificially reduce and increase the band of the RF dispersions and evaluate the impact on the linearity. The purpose of these simulations is to advise the designer of the required RF bandwidth to achieve the mandatory linearity performance. The designer will then adjust its circuit accordingly to maximize the efficiency-linearity trade-off.","PeriodicalId":207437,"journal":{"name":"2023 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129132411","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}

Since a real receiver never shows a perfect linear characteristic, this always implies nonlinear effects. Consequently, the in the receiver generated interfering signals lead to a reduced total sensitivity. According to the intensity and spectral distribution of the input signals, intermodulation noise is produced. This paper shows a consideration and an estimation of nonlinear effects in different receiver architectures, depending on various measured input spectra for passive FM radar.","PeriodicalId":207437,"journal":{"name":"2023 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129731613","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 operation mode can be tuned from Class-AB to Class-A by simply adjusting the VDD.
