1. A miniature microwave component comprising:

  • an MMIC microwave chip encapsulated in an individual package for surface mounting, the chip having an active face, which includes electronic elements and electrical conductors on the active face, and, opposite the active face, a rear face which includes electrical conductors on the rear face and among these conductors on the rear face an electrical conductor forms a ground plane;

    a metal base for mounting the chip in the package via its rear face, said base having an aperture; and

    two access ports for the communication of electrical signals between the inside and the outside of the package, a contactless microwave access port, by electromagnetic coupling at the aperture in the base, ensuring transmission of coupling signals at a working frequency F0, a subharmonic access port via a contact, for inputting, into the integrated circuit, a subharmonic frequency F0/n of the working frequency F0,wherein the chip includes, among its electrical conductors, a coupling electrical conductor connected to the electronic elements of the chip, the coupling conductor being placed at the contactless microwave access port in order to transmit microwave signals by electromagnetic coupling at the working frequency F0.
