    • High frequency power amplification modules comprise a dielectric substrate supporting a stepped impedance transition coupled to the input of a power amplifier and a symmetrically disposed stepped impedance transition connected to the output of the power amplifier. The power amplification modules are oriented in an electromagnetic energy field so that input electromagnetic energy is coupled to the input of the power amplifier by the input side stepped impedance transition, amplified by the amplifier, and emitted from the module by the output side stepped impedance transition. A plurality of the power amplification modules may be organized into an array to provide a power combiner. The power amplification modules in the array may be linked by isolation impedances that decouple the modules in the array.

    • An n-stage RF choke comprises a series connection of two or more inductors connected in series between a source and a load. The inductor closest to the source has the largest inductance and the inductance closest to the load has the smallest inductance. The inductances of any inductors between the inductor closest to the supply and the inductor closest to the load decrease as a function of distance from the supply. The junctions between the inductors in the series connection are shunted to ground by capacitors connected in series with resistors that provide a matched termination for increasing bandwidth by lowering circuit Q factors and eliminating resonant frequencies. The capacitor closest to the supply has the largest capacitance and the capacitor closest to the load has the smallest capacitance. Any intermediate capacitors decrease in capacitance as a function of distance from the supply. Such an arrangement provides a high impedance that isolates the load from the supply at a wide range of frequencies.
    • n级RF扼流圈包括在源极和负载之间串联连接的两个或更多个电感器的串联连接。 最靠近源极的电感具有最大的电感,最靠近负载的电感具有最小的电感。 最靠近电源的电感器和最靠近负载的电感器之间的任何电感器的电感随着电源距离的减小而减小。 串联电感器之间的接点通过与电阻器串联连接的电容器分流到地,这些电阻器通过降低电路Q因数并消除谐振频率来提供匹配的端接以提高带宽。 最靠近电源的电容具有最大的电容,最靠近负载的电容具有最小的电容。 任何中间电容器都会随着电源距离的减小而减小。 这种布置提供了高阻抗,其在宽范围的频率下将负载与电源隔离。
