Distributed radiohead system

A radio frequency circuit, comprising:

• a layer in a plane comprising a radio frequency front-end to antenna (RF FE-to-Ant) connector, the RF FE-to-Ant connector comprising a conductor track structure along a plane of the layer;
• and
• a first layer connection structure coupled to the conductor track structure in the plane, wherein the first layer connection structure comprises at least one of a solderable structure, a weldable structure, or an adherable structure, wherein the first layer connection structure is configured to form at least one radio frequency signal interface with an antenna circuit connection structure of a layer-external antenna circuit;
• wherein the layer further comprises radio frequency front-end circuitry monolithically integrated in the layer and a second layer connection structure coupled to the radio frequency front-end circuitry;
• and
• wherein the second layer connection structure comprises at least one of a solderable structure, a weldable structure, or an adherable structure, and the second layer connection structure is configured to form at least one radio frequency signal interface with a cable of a layer-external digital interface, wherein the first layer connection structure is disposed in the plane at an edge region of the layer, wherein the layer and the layer-external antenna circuit are arranged coplanar with one another, wherein the first layer connection structure is configured to mate in the plane with the antenna circuit connection structure to form the at least one radio frequency signal interface.
