    • A MMIC power amplifier having 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.” In a shared input configuration, a compensation network may be coupled to the input. 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.”
    • 具有较小管芯尺寸和较高功率输出的MMIC功率放大器通过本文提供的改进的放大器和晶体管几何结构来实现。 特别地,诸如FET(场效应晶体管)的晶体管从传统的FET几何形状中移位,交变的FET沿相反方向旋转。 两个相邻FET的输入(栅极焊盘)和输出(漏极焊盘)可以“共享”。 在共享输入配置中,补偿网络可以耦合到输入。 改进的FET配置将分离和组合网络的数量减少了高达现有技术的50%,并且典型的4瓦功率放大器的管芯面积比现有技术减少了48-72%。 改进的放大器配置提供多截面配置,其中一个部分可以是另一部分的镜像。 在两段放大器中,放大器似乎是“折叠的”。

    • In an exemplary embodiment, a spurline filter comprises a capacitive element connected to a spur and either a through-line of the spurline filter or ground. In another embodiment, multiple capacitive elements are connected to the spur. In an exemplary embodiment, the capacitively loaded spurline filter provides a band rejection frequency response similar to the band rejection frequency response of a similar spurline filter that does not comprise at least one capacitive element but the capacitively loaded spurline filter has half the layout area or less. In an exemplary embodiment, the spurline filter comprises capacitive elements, where the capacitive elements are configured to reduce the resonant frequency of the filter.

    • Doherty and distributed amplifier (DA) designs are combined to achieve, wideband amplifiers with high efficiency dynamic range. A modified Doherty amplifier includes a wideband phase shifter providing first and second outputs, a main amplifier coupled to the first output, an auxiliary amplifier coupled to the second output, and a wideband combining network combining the outputs in phase. A multi-stage DA has a main output and a termination port, and a phase delay module and transforming network allowing power at the termination port to be combined in phase with power at the main output. In one combination, one or more stages of the DA may comprise a Doherty amplifier. In another combination, a modified series-type Doherty amplifying system is achieved by cascading main and auxiliary DAs. In any combination, Doherty topology may include a bias control module.
