Publication number: 20240047854Abstract: The present invention relates to a millimeter wave RF antenna array apparatus. The apparatus comprises a single-chip MMIC comprising active circuit elements of the antenna array apparatus. The active circuit elements comprise at least antenna feed circuitry configured to feed antenna elements of the antenna array. The apparatus comprises an interposer fabricated of low-loss RF material, such as glass, low-temperature co-fired ceramic, LTCC, or printed circuit board, PCB. The interposer comprises transmission lines of a RF distribution network and a plurality of antenna elements of the antenna array. The transmission lines of the interposer are coupled to the MMIC for providing RF connections for distributing RF signals to and from the antenna feed circuitry. Area of the interposer that comprises the transmission lines of the RF distribution network and the plurality of antenna elements is collocated with the area of the MMIC that comprises said antenna feed circuitry.Type: ApplicationFiled: December 3, 2021Publication date: February 8, 2024Applicant: Teknologian tutkimuskeskus VTT OyInventors: Vladimir ERMOLOV, Antti LAMMINEN

Publication number: 20220166122Abstract: A hybrid millimeter-wave Wilkinson divider comprises an input port (1), a first output port (2), a second output port (3), and transmission lines connecting the input port (1) to the first and second output ports (2, 3) implemented by transmission lines in a carrier substrate (PCB, 31). An isolation resistor of the Wilkinson divider connected between the first and second output ports (2, 3) is integrated in a monolithic micro-wave integrated circuit (MMIC) chip (40) installed on the carrier substrate. On the MMIC chip the isolation resistor is connected between RF input metal pads. A compensation circuit for parasitic capacitances caused by the RF input metal pads is provided on the MMIC chip (40) so that the on-chip resistor appears as a pure resistance to the output ports (2, 3) of the Wilkinson divider on the carrier substrate (PCB, 31).Type: ApplicationFiled: March 17, 2020Publication date: May 26, 2022Inventors: Mikko VARONEN, Antti LAMMINEN
