Abstract

Low conversion loss (CL) and high isolation graphene harmonic mixer with inductor-capacitor resonators and microstrip reflective stubs (MRS) is presented in this paper. The nonlinear electromagnetic field characteristics of the multilayer graphene are similar to those of an antiparallel diode pair, which has very strong nonlinear characteristic and is suitable for the development of the Low-level even-combinatorial-frequency harmonic mixer. Through the reflection of radio frequency (RF) signal and local oscillator (LO) frequency signal, the CL of graphene harmonic mixer is significantly reduced, and the isolation between the ports is also improved. The measured minimum CL at the LO power of 16dBm is about 19.2dB, and 2-3dB lower than that without MRS over the frequency band from 2.05-2.5GHz, while the isolation between ports is better than 30dB.
