摘要： A MMIC (microwave monolithic integrated circuit) driver amplifier having a zig-zag RF signal flow and method for the same is provided. A smaller die size and higher output gain are realized with the improved amplification stage geometry provided herein. In particular, the stages are configured in a “stacked” topology permitting a zig-zag RF signal flow through the stages. Additionally, the DC bias circuitry may be is centralized and adjacent stages may share vias. The die area for a typical K-band driver amplifier may be reduced by about 56% over a conventional amplifier design.

摘要： A MMIC (microwave monolithic integrated circuit) power amplifier and method for the same is provided. A smaller die size and higher power output are realized with the improved amplifier and transistor geometry herein provided. In particular, transistors, such as FETs (field effect transistors) are displaced from a conventional FET geometry with alternating FETs being rotated in opposite directions. The inputs (gate pads) and outputs (drain pads) of two adjacent FETs may be “shared.” The improved FET configuration reduces the number of splitting and combining networks by up to 50% over the prior art and the die area for a typical 4 watt power amplifier is reduced by 48-72% over the prior art. The improved amplifier configuration provides a multi-sectional configuration wherein one section may be the mirrored image of another. In a two section amplifier, the amplifier appears to be “folded.”

摘要： A power amplifier uses a plurality of solid-state amplifiers (FIGS. 2 and 3, 140) arranged in a parallel manner to form a power amplifier module (10). Each solid-state amplifier is adhered to a low thermal expansion insert (130). The insert is then coupled to a low cost aluminum substrate in order to carry the excess heat from each solid-state amplifier (140) to the aluminum housing. The power outputs from the solid-state amplifiers from each module are combined with the power outputs from other modules using electroformed waveguide combiners (FIG. 1, 30, 40).

摘要： A method and apparatus for power combining or dividing handles high impedance line requirements in n-way combiners (15) and dividers (10) using phase delay networks (12, 14) to transform impedances to a lower, intermediate impedance. Each impedance transformation is accomplished using a stepped impedance or tapered impedance transmission line (26). The method and apparatus provides isolation between input or output ports (11, 22 and 24, 13) in power combining or dividing circuits using an incremental phase delay network (12) of prescribed electrical phase lengths (22, 24) to provide phase cancellation. The power divider (10) and combiner (15) can be used in power amplifiers and in communication devices.

摘要： In an exemplary embodiment, a phased array solid-state architecture has dual-polarized feeds and is manufactured, for example, on highly flexible silicon germanium (SiGe). The implementation of dual-polarized feeds facilitates the operation of phased arrays where the polarization can be statically or dynamically controlled on a subarray or element basis. In an exemplary embodiment, the sub-component control is configured to optimize a performance characteristic associated with polarization, such as phase or amplitude adjustment. An active phased array architecture may replace traditional distributed and GaAs implementations for the necessary functions required to operate electronically steerable phased array antennas. The architecture combines active versions of vector generators, power splitters, power combiners, and RF hybrids in a novel fashion to realize a fully or substantially monolithic solution for a wide range of antenna applications that can be realized with radiating elements having single-polarized or dual-polarized feeds.

摘要： A multistage amplifier and design method are disclosed. The multistage amplifier has a plurality of amplifier stages, each stage having an amplifier designed and biased to operate at or near the amplifier's power added efficiency (PAE) peak. The PAE peak of each of the amplifier is at or near the amplifiers linear-compression transition region, providing a multistage power amplifier that is power efficient and has desirable amplitude to amplitude and amplitude to phase power transfer characteristics. The amplifier is designed by matching the output impedance of a final stage with a load. Amplifier stages are iteratively designed from the last stage to the first. At each stage, an amplifier and drive circuit are designed. The drive circuit and amplifier are designed to provide each stage with output impedance matched to the input impedance of the following stage and to operate at or near the PAE peak of the amplifier.
