Abstract:
A capacitively coupled distributed amplifier comprising:an input transmission line including a plurality of input inductors, said input transmission line further including an input termination resistor; an output transmission line including a plurality of output inductors, said output transmission line further including an output termination resistor; a plurality of distributed amplifying devices electrically connected to the input transmission line and the output transmission line; a feedback regulator electrically connected to the output termination resistor, said regulator sensing a voltage potential across the output resistor and comparing the voltage potential to a reference potential, said regulator providing an output signal to the amplifying devices indicative of the difference between the sensed voltage potential and the reference potential; and a distributed transmission line filter electrically connected between the feedback regulator and the input termination resistor, said transmission line filter filtering RF signals from the output transmission line.
