LTCC Transmit/Receive X-Band Module with a Phased Array Antenna 3 www.cadence.com/go/awr 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. Figure 4: Detail of the TX/RX module subcircuit 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.
