The proposed D-band PA consists of four push-pull PA units with three stages, whose active device sizes are gradually tapered from the output to the input optimal power efficiency. A cascaded transformer-transformer (balun) structure was employed at the output of the PA unit to avoid self-resonance with an improved balun performance at the D-band. The power combiner/splitter is comprised of microstrip transmission lines (MSTLs) to combine the power of the four PA units in the current domain. The fabricated prototype has a chip size of 0.72 mm2 with a core size of 0.46-mm2 excluding pads. The measured PA achieved a power gain of 14.5 dB with the 3-dB gain bandwidth of 18 GHz (121–139 GHz), a peak PAE of 7.2%, and a saturated output power (\u0000<inline-formula> <tex-math>$P_{mathrm {sat}}$ </tex-math></inline-formula>\u0000) of 16.5 dBm, which demonstrates the highest output power among the recently reported D-band PAs in bulk CMOS.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141964826","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}

For each input port excitation in this proposed network, a continuous 120° tunable progressive phase difference is obtained at the output ports, and the full 360° tunable phase progression is achieved by exciting all three input ports. Most importantly, all tuning range relaxed phase shifters are controlled simultaneously by only two-channel dc voltages to achieve full progressive phase tuning range, which can simplify the control method of beam steering. Compared to the conventional feeding matrix, the proposed design achieves a flexible progressive phase, compact size, easy control, and low power consumption. The theoretical analysis is carried out for the proposed circuit topology, and the closed-form equations are derived to minimize the phase shifter’s tuning range and reduce the control complexity. To verify the proposed design concept, a prototype tunable Nolen matrix operating at 5.8 GHz is designed and tested, and the experimental results agree well with simulation and theoretical analysis.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141965788","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 coupler is fabricated through metal copper additive manufacturing process. To mitigate the impact of the polymer strips on the coupler’s raw directivity, the coupled lines were designed with a special impedance function, which effectively increases the average spacing between them, so the parasitic couplings from the polymer can be reduced. Additionally, enhancements to the polymer fabrication process now allow for the supporting strips to be meshed, further enhancing the directivity of the coupler.
