Abstract :
In this contribution, we describe an advanced mixed-mode physics-based device simulator applied to the estimation of the noise properties of microwave mixers. The drift-diffusion model, and a proper set of circuit equations describing the device embedding network, is solved in the frequency domain with the harmonic balance approach. The cyclostationary device noise properties are then numerically estimated, and used to calculate the system mixer noise performances. An example of application to a downconversion GaAs MESFET mixer is reported to demonstrate the simulator capabilities
