    Abstract: A wide bandwidth planar four port MMIC transformer is provided by input diplexers which divide up the incoming signal into a high band and a low band, with the resulting signals coupled to high band and low band four port transformers implemented in one embodiment using spiral inductors and coupled lines, the outputs of which are combined using two output diplexers to provide a decade bandwidth transformer.

    Abstract: The replacement and elimination of duplexers in a tightly coupled dipole phased array starts with transmit and receive functions physically separated and having different antenna port feeds. The simple coupling network used with tightly coupled dipole arrays is replaced by a state switch which alternates between a coupling state and a dipole feed connection state. The basic method can be applied to antenna apertures of various kinds, including both linear and dual polarized versions. The ability to locate state switches at various nodes in tightly coupled dipole phased arrays permits flexibility in antenna design and eliminates bulky and lossy components, simplifies the design requirements and allows independent optimization of the components.

    Abstract: A MMIC amplifier is directly connected to the balanced feed points at the aperture of an antenna to eliminate the distance between electronics coupled to the antenna and the antenna itself, such that interfaces, components and connection lines which introduce losses and parasitic effects that degrade system performance are eliminated due the direct connection. Expanding the aperture of the antenna to accommodate the direct connection of a MMIC amplifier to balanced feed points of an antenna has been found to have no deleterious effects on antenna performance. Moreover, when coupling the MMIC amplifier to an unbalanced coaxial line, any associated ripple is minimized due to the direct connection.
