Abstract: Apparatus, methods and articles of manufacture are disclosed for modifying electromagnetic waves by reducing noise in those waves. A transfer function for a plurality of segments is derived through identifying a desired output parameter. That transfer function is then applied, via a plurality of filters or other devices, to a wave, in order to achieve said transfer function.

Abstract: Apparatus, method and article of manufacture are shown for linear signal modification. An input signal is modified by providing one or more non-linear current sources and regulating at least one of the one or more current sources to output a signal based on one or more of the input signal characteristics. The modification of the output signal includes both amplification and attenuation.

Abstract: A planar MESFET transistor includes a plurality of FET elements (1) including a doped planar channel (351), and source (301) and drain (302) coupled to the ends of the channel (351). A gate conductor (51) extends over a portion of the channel (351) at a location lying between the source (301) and drain (302), a first predetermined distance (L1) from the drain. A field plate (240) is connected to the gate conductor (51), extends toward the drain (302)a second predetermined distance (L2), and is isolated from the channel (351) except at its gate conductor connection by a dielectric material (340).

Abstract: A precision signal delay apparatus and method for introducing time delay to a signal. Precision delay is introduced by a pair of delay locked loops (DLLs) connected in series each with selectable delay (i.e., a Vernier-type circuit). Nonumformity in the precision delay is compensated with a delay compensation circuit. The apparatus and method may be used for phase shifting, data delay, precision pulse width modulation, and precision time windowing.

Abstract: A ferrite phase shifter includes a waveguide having a first cylinder and a second cylinder, the radius of the second cylinder being less than the radius of the first cylinder. The second cylinder is disposed within the first cylinder such than the two cylinders have a common axis symmetry. The waveguide includes a first septum formed as a disk and disposed within the second cylinder. The disk has a pie-shaped aperture formed therethrough and is centrally disposed within the second cylinder so that the two cylinders and the disk share the same axis of symmetry. The second cylinder has a opening formed therethrough that is aligned with the pie-shaped aperture. The waveguide further includes a second septum that extends from the first cylinder to the disk center while bisecting the pie-shaped aperture.
