Ultra-broadband Programmable Hybrid Step Attenuator

摘要

Systems and methods for partitioning the frequency spectrum for use in a plurality of function circuits, including step attenuation, phase modulation, and gain amplification functional circuits. A system may include a programmable step attenuator including selection circuitry and functional circuitry. First selection circuitry may include a plurality of outputs and may receive a signal and selectively provide the signal to an output based on the signal's frequency. First circuitry may be coupled to one of the outputs and may operate as a first step attenuator for signals in a first portion of the frequency spectrum. Second circuitry may be coupled to another output and operate as a second step attenuator for signals in a second portion of the frequency spectrum. Second selection circuitry may be coupled to the first and second circuitry and may provide a step attenuated signal from the first or second portion of the frequency spectrum.
