    RF waveguides are devices that transmit energy from one place to another. Instead of radiating energy directly into the entire space like an antenna, the microwave waveguide can confine the energy in a hollow metal, which greatly reduces the loss during energy transmission. The millimeter wave waveguide can be understood as a particularly strong directional antenna, and the energy can only be propagated in the waveguide, and cannot be diffused elsewhere.
    Waveguide transition is one of the waveguide , widely used in a variety of fields, including but not limited to microwave communications, radar systems, communication satellites and microwave radio link equipment. There are many kinds of waveguide transitions, usually with high performance, typical standing wave VSWR≤1.2 within the full waveguide bandwidth, basic materials including copper, aluminum, surface treatment methods silver plating, gold plating, nickel plating, passivation, conductive oxidation, etc.

    Features:

    The typical feature of the transition waveguide is that the two ports use different waveguide types for conversion between different waveguide types. For example:
    1. Waveguide to microstrip converters: Waveguide to microstrip converters are widely used in the detection of millimeter wave monolithic integrated circuits and hybrid circuits, as well as in the connection of waveguide to planar circuits to ensure a well-matched transition between the two transmission lines.
    2. Transition from double-ridged waveguides to rectangular waveguides: Precision machined transition waveguides can connect double-ridged waveguides to rectangular waveguides, providing low insertion losses and high matching. This kind of transition waveguide is suitable for laboratory installation and measurement of double-ridged rectangular waveguide assembly and equipment
    3.  Rectangular waveguide transition: The rectangular waveguide uniformly converts TE10 mode in a standard rectangular waveguide to TE11 mode in a circular waveguide. This conversion is important for efficiently transmitting signals from a standard rectangular waveguide to a circular waveguide, especially in applications where this specific mode conversion is required

    Qualwave supplies waveguide transitions cover the frequency range up to 220GHz, as well as customized waveguide transitions according to customers requirements.
