Abstract: A branchline coupler structure having a pair of main transmission lines disposed on different horizontal levels of a support structure and a pair of shunt transmission lines, vertically disposed and laterally spaced, and disposed in the support structure. A first one of the pair of shunt transmission lines is coupled between: one region of a first one of the pair of main transmission lines and a first end of a second one of the pair of main transmission line. A second one of the pair of shunt transmission lines is coupled between a second region of the first one of the pair of main transmission lines, laterally spaced from the first region, and a second end of the second one of the main transmission lines.

Abstract: An amplifier having a Radio Frequency (RF) power level detector circuit for producing a control signal in accordance with a power level of an RF input signal. The control signal indicates whether the power level of the input signal is within a predetermined range of power levels greater than zero. A bias circuit is fed by the control signal, for producing a fixed bias voltage at a gate electrode of a field effect transistor (FET) to establish a predetermined quiescent current for the FET when the control signal indicates the power level of the RF input signal is within the predetermined range of power levels and to reduce the bias voltage to reduce the predetermined quiescent current when the control signal indicates the power level of the RF input signal is below the predetermined range of power levels.

Abstract: A phase shifter is formed by providing a branchline coupler having a pair of phase adjusting sections. Each one of the phase adjusting sections is coupled to a corresponding one of a pair of shunt transmission line sections of the branchline coupler. Each one of the pair of phase adjusting sections includes: first and second conductive pads are disposed on the surface of a substrate having a gap between them; one of the pads being connected to a ground plane conductor on a bottom surface of the substrate. A series of conductive layer segment is sequentially written on the surface of the substrate in the gap electrically connected to sidewalls of the first and second pads. Phase shift through the phase shifter is measured after each one of the segments is written. The writing process is terminated when the measuring detects a predetermined phase shift through the phase shifter.

Abstract: A microwave transmission line structure having a pair of ground strip conductors on a surface of a dielectric substrate structure. A signal strip conductor is disposed on the surface of the dielectric substrate structure between the pair of ground strip conductors. A solid dielectric layer is disposed over: the signal strip conductor; the upper surface of the dielectric substrate structure between sides of each one of the ground strip conductors; and the signal strip conductor. An electrically conductive shield member is disposed on the solid dielectric layer and on, and in direct contact with, upper surfaces of the pair of ground strip conductors. The structure is used on each one of a plurality of proximate microwave transmission lines formed on the substrate structure to electrically isolate the transmission line.
