La demande croissante de fréquences à ondes millimétriques (mmWave) avec des bandes passantes de signal plus larges, telles que la 5G NR, nécessite d'importants investissements dans les équipements de test. Ce travail présente un convertisseur ascendant/abaisseur 5G mmWave avec un LO de 40 GHz, fabriqué dans des PCB personnalisés avec des composants disponibles dans le commerce. Le convertisseur mmWave a de larges bandes passantes IF et RF de 1∼5 GHz et 21∼45 GHz, et le LO intégré génère 20∼29.5 GHz et 33.5∼40 GHz de sortie. Pour obtenir simultanément une linéarité élevée du convertisseur, le LO doit produire un faible bruit de phase et être capable d'un rejet élevé d'harmoniques et de parasites, et les techniques de conception liées à ces caractéristiques sont démontrées. De plus, un amplificateur FI reconfigurable pour la conversion bidirectionnelle est inclus et démontre une faible variation de gain pour maintenir la linéarité des signaux de modulation à large bande. Le convertisseur final conçu est testé avec des signaux 5G OFDM 64-QAM 100 MHz 1-CC (4-CC) et affiche une puissance de sortie RF/IF de -3/8 dBm avec une plage linéaire de 35 (30)/38 (33). dB à un EVM de 25 dB.

Abstract: The increasing demand for millimeter-wave (mmWave) frequencies with wider signal bandwidths, such as 5G NR, requires large investments on test equipment. This work presents a 5G mmWave up/down-converter with a 40 GHz LO, fabricated in custom PCBs with off-the-shelf components. The mmWave converter has broad IF and RF bandwidths of 1∼5 GHz and 21∼45 GHz, and the built-in LO generates 20∼29.5 GHz and 33.5∼40 GHz of output. To achieve high linearity of the converter simultaneously, the LO must produce low-phase-noise and be capable of high harmonics/spur rejection, and design techniques related to these features are demonstrated. Additionally, a reconfigurable IF amplifier for bi-directional conversion is included and demonstrates low gain variation to maintain the linearity of the wideband modulation signals. The final designed converter is tested with 5G OFDM 64-QAM 100 MHz 1-CC (4-CC) signals and shows RF/IF output power of -3/8 dBm with a linear range of 35 (30)/38 (33) dB at an EVM of 25 dB.
