An RF power divider circuit unequally divides an input signal into first and second signal components of unequal power. The circuit includes a single input port, first and second output ports, and a combination of a plurality of quarter wave transformers and a plurality of resistors coupled between the input port and the first and second output ports.

A microwave attenuator circuit is disclosed, including a combination of a plurality of quarter wave transformers and a plurality of resistive elements.

Attenuator circuit comprising a plurality of quarter wave transformers and lump element resistors

A foldable radiator assembly includes a flexible dielectric substrate structure having a radiator conductor pattern formed therein. The flexible substrate structure can be flexible for movement between a folded position and a deployed position, or can be fixed in position by dielectric structures. An excitation circuit excites the radiator conductor pattern with RF energy. Strips of the radiator assemblies can be used to form an array aperture.
