New topology of the GaAs non-linear transmission line (NLTL) using microstrip line technology

A novel NLTL is designed using microstrip as an alternative to the coplanar wave guide (CPW) approach which has the advantage of reduced chip size and cost. A frequency multiplier has been designed with the number of sections optimized for power output using harmonic balance simulation. The large and small signal models of the 4*75 /spl mu/m GaAs schottky diode which is used in the design are verified using S-parameters and large signal measurements.
