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

An adaptable microwave radio transceiver system having a microwave radio transceiver and at least two waveguide adapters, where the microwave radio transceiver is adapted for at least two waveguide frequency bands and includes at least one radio port that includes a corresponding probe of a fixed length and extends via an inner insulating part in a bottom in the corresponding radio port. Each waveguide adapter has a first end facing the corresponding bottom where each first end includes a bottom wall with an outer insulating part through which the corresponding probe is adapted to protrude a protrusion distance. The protrusion distance is dependent on a thickness of the bottom wall, where at least two waveguide adapters have different thickness of the corresponding bottom wall, where any one of the waveguide adapters is exchangeably mountable to the radio port.
