Abstract
A broadband frequency doubler using left-handed nonlinear transmission lines (LH NLTLs) based on MMIC technology is reported for the first time. The second harmonic generation on LH NLTLs was analyzed theoretically. A four-section LH NLTL which has a layout of 5.4 × 0.8 mm2 was fabricated on GaAs semi-insulating substrate. With 20-dBm input power, the doubler obtained 6.33 dBm peak output power at 26.8 GHz with 24-43 GHz -6 dBm bandwidth. The experimental results were quite consistent with the simulated results. The compactness and the broad band characteristics of the circuit make it well suit for GaAs RF/MMIC application.-
