摘要： A 90 degree hybrid is contemplated having three parallel signal paths, one of the signal paths is a central signal path which provides direct impedence to ground. The other two signal paths are capacitively coupled to the central signal path to provide a second impedence. Each signal path incorporates at least one inductor coupled in series along each of the signal paths. The signal paths are capacitively coupled to each other at each end of the inductors. To increase the bandwidth, additional hybrids are coupled in series, with each hybrid forming a section of the broadband hybrid.

摘要： A high isolation microwave module includes a housing floor with mounting surfaces for placing microwave components and housing walls ending in housing wall ends coupled to and projecting from the housing floor. A lid including a lid plate and lid walls ending in lid wall ends projects from the lid plate. The lid walls extend toward the housing floor and the plurality of housing walls extend toward the lid plate but neither the lid wall ends nor the housing wall ends are coupled to the housing floor or lid plate, respectively. A plurality of cavities exist between the adjacent lid walls between the housing and the lid plate and a plurality of irises exist between immediately adjacent housing walls and corresponding lid walls. The irises and cavities act as a multi-section high pass filter to provide attenuation to a microwave signal passing through the module.

摘要： An improved broadband mixer includes a first balun (11) with a first signal port (12), a second balun (14) with a second signal port (15), a third balun (17) with a third signal port (18), and a frequency converter (19) coupled between the first, second, and baluns. The first balun means, which preferably receives an RF signal via said first signal port, includes two juxtaposed ground plane baluns 31 and 32 each having opposed, spaced, strip conductors in different planes. The second balun, which preferably receives an LO signal via the second signal port, has a coplanar balun (44) including three strip conductors in the same plane which in turn connects to two juxtaposed ground plane baluns (45 and 46) each having opposed, parallel spaced, strip conductors. The combination of the coplanar balun (44) with the two ground plane baluns (45 and 46) establishes signal polarities which merge end to end with the opposite ground plane baluns (31 and 32) to prevent signals from passing from one signal port to the opposite signal port without requiring cross-connections between the strip conductors in different planes opposite the ground plane baluns.

摘要： A broadband 180 degree hybrid having lumped or semi-lumped elements is comprised of a network of low and high pass filters. A 180 degree phase differential is obtained by splitting an input signal from a first input. A first portion of the split signal is passed through a low pass filter and a second portion is passed through a high pass filter. The phase differential is maintained at 180 degrees. A zero (0) degree phase differential is obtained by splitting an input signal from a second input and passing both portions through a pair of low pass filters or through a pair of high pass filters.

摘要： A dielectric resonator oscillator (DRO) (200, FIG. 2; 600, FIG. 6; 900, FIG. 9) includes a dielectric resonator (202, 602, 902) that is held in a fixed position with respect to the housing lid (206, 606, 906). In one embodiment, the resonator is attached to the housing lid using one or more support legs (208). In another embodiment, the resonator is attached to the housing lid using a ring structure (608). In still another embodiment, the resonator is attached to the lid and housing (904) using a lid tuner (914) and lid pedestal (908), and a housing tuner (915) and housing pedestal (909). Resonator positioning within the DRO cavity (222, 622, 922) is simplified by accurately aligning and attaching the support structure to the resonator.

摘要： A mixer separates IF components IF1, IF2 of the same frequency which are images of different frequency RF signals RF1, RF2 beating with a given LO signal. The LO signal is applied to a FET active power divider and applied to the drains of a pair of balanced FET mixing elements. The FETs for the active power divider are built from the same device structure as the FETs for the mixing elements sharing drain nodes. The RF signals are passed through a quadrature phase shifter and applied to the gates of the FET mixing elements. The mixed signals appear at the drains of FET mixing elements are applied to opposing ports of a second quadrature hybrid at whose output ports the separated IF output signals IF1, IF2 appear.

摘要： A logarithmic amplifier includes amplifier stages having an input transmission line and first and second output transmission lines. The input and output transmission line are coupled by multiple amplifier elements distributed along the transmission lines. One output transmission line forms a high gain low compression path and the other a low gain high compression path. The output transmission lines of each stage are coupled to a combiner from whence the logarithmically amplified output signal is obtained. The logarithmic amplifier stages are readily constructed in MMIC form and multiple stages may be easily cascaded to provide a very large dynamic range.
