Figure 4 highlights the TX/RX module subcircuit, which was modeled in the AWR VSS software with behavioral models. Inside
the subcircuit are the switches, filters, and amplifiers; the mixers and other components are shown outside the model.

After building the system design, the RF budget (RFB) utility within the AWR VSS software was used to make RF cascaded
measurements such as gain, noise figure, and third-order intercept. The RF inspector (RFI) frequency-domain utility in the
AWR VSS software was then used for spurious analysis of the TX mode and RX mode (Figure 5) of the module.
