The present disclosure relates to a capacitively-coupled distributed amplifier (DA) having an input line and an output line that are coupled to one another through a broadband interface network and DA segments. The input line receives an input signal and the output line provides an output signal based on amplifying the input signal. The broadband interface network includes a group of capacitive elements coupled between the input line and the DA segments to extend a gain-bandwidth product of the DA. The broadband interface network further includes a resistor divider network coupled between the input line and the DA segments to extend a lower end of an operating bandwidth of the DA. As such, the operating bandwidth of the DA may extend from baseband frequencies to microwave frequencies.
