The proposed fundamental and harmonic matching is achieved using an output transformer with an embedded capacitor for continuous inverse class-F operation. In this way, we can reduce the harmonic load complexity and insertion loss greatly. Therefore, the proposed inverse Class-F PA shows a saturated output power (Psat) of 17.9 dBm, output power bandwidth (30 to 40 GHz) with 33 % peak PAE, and output 1-dB compression point (OP1dB) of 15.0 dBm at 34 GHz. When tested with a single-carrier 64-QAM signal, this PA achieves bandwidth of 400 MHz, 14.1-dBm average output power, and 22.1% average PAE under root-mean-square (rms) error vector magnitude (EVM) −25.1 dB. Among all the published mm-Wave CMOS PAs, this PA shows outstanding large-signal performances and exceptional modulation capability.","PeriodicalId":283714,"journal":{"name":"2020 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115071407","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}

By pure formulation, we explore the trajectories that will appear on the plane from this local magnification.

Integrated into a very compact area of $202mumathrm{m}times 164mumathrm{m}=0.033 text{mm}^{2}$, the proposed design has achieved −11 dBm output power and −10 dB conversion gain with an output −3 dB bandwidth over 16 GHz.

In the in-body condition, the operating frequency becomes lower than that in out-body condition due to the higher dielectric constant of surrounding medium (i.e. human body and liquid) of the antenna. From the EM simulation result, we found that this tag can be operated at 920 MHz-band which is commonly used in existing 920 MHz RFID system.
