A broadband GaAs MMIC frequency doubler on left-handed nonlinear transmission lines
摘要
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.关键词
