  • Publication number: 20240063521
    Abstract: A transversal radio frequency filter circuit having a low noise amplifier connected along an input signal path, a first power divider connected between the low noise amplifier and four single taps, and an output path connected to the outputs of each of the four single taps. Each of the four single taps having a coefficient control mechanism, a polarity selection mechanism, and a time delay element. The coefficient control mechanism can include a wideband digital step attenuator configured to support high control range of the coefficient. Additionally, the circuit can include a second power divider connected between the outputs of each of the four single taps and the output path. The circuit can further include a field-programmable gate array configured to control coefficient control mechanisms, the polarity selection mechanisms, and the time delay elements (when they are variable time delay elements).
