The present disclosure relates to oscillator arrangement comprising an output port adapted to output an output signal with an output frequency (f), an in loop oscillator that is adapted for an in loop oscillator frequency (f) and an additional oscillator that is adapted for an additional oscillator frequency (f). The output frequency (f): exceeds the in loop oscillator frequency (f) and the additional oscillator frequency (f), is dependent on both the in loop oscillator frequency (f) and the additional oscillator frequency (f), and is adapted to control the in loop oscillator frequency (f) via a feed-back loop.

Oscillator arrangement with improved phase-noise properties

The present invention relates to a metalized waveguide interface () for providing a galvanically isolated waveguide connection for a propagating signal, between a standardized waveguide () and a, to the standardized waveguide non-compatible, metalized chip-level waveguide ().
