Notes/Equations
- MixerWithLO is a two port mixer model with internal oscillator.
- This component is a schematic design that uses internal models for Mixer2 and I_1Tone. The schematic design is shown here:
- See documentation for the internal components Mixer2 and I_1Tone for their usage detail.
- The internal Mixer2 model has parameter SideBand=BOTH. This MixerWithLO outputs both the RF+LO and RF-LO sidebands. However, there is no RF or LO leakage.
- Internal to the Mixer2 model, the NF parameter is used to set the Mixer2 parameters for NFmin=NF, Sopt=0, and Rn=max( ZRef/4 × (10NF/10-1), tinyreal), where tinyreal is an internal simulator value for the smallest real value allowed.
- For use with Budget Analysis, the DesiredRF parameter identifies which of the output sidebands is to be tracked for Budget measurements.
- Regarding SOI and TOI, the MixerWithLO must be output-matched in order to validate SOI and TOI.
By default, SOI and TOI are blank resulting in no nonlinearity. TOI may be set without setting SOI. However, if SOI is set, then setting TOI is required. For more information about SOI and TOI, refer to the Mixer2 component documentation. - Examples demonstrating this model use in a Budget analysis are located in the ADS Examples area at: $HPEESOF_DIR/examples/Tutorial/RF_Budget_Examples_prj.
