Abstract : A fully monolithic solid state device compatible with standard semiconductor processing for amplifying radio frequency (RF) microwave and/or millimeter wave signals is disclosed. The device includes an input microstrip transmission line which capacitively couples an input RF signal to input underlying grating fingers which, in turn, mode-couple the signal to an interaction grating region by way of an input finger taper region. The RF is amplified in the interaction grating region through its interaction with a space charge wave. Then the amplified RF signal is mode-coupled to output underlying grating fingers by way of an output finger taper region before it is capacitively coupled to an output microstrip transmission line.
