S-Parameter Test Setup

GUID-20220825-SS0I-XHWC-3R0S-2DS95GXPP0XG-low.svg Figure 3-1 S-Parameter Test Setup

Use the following guidelines for S-parameter measurement:

  1. As Figure 3-1 shows, the S-parameter is typically measured using a Vector Network Analyzer (VNA). For measuring the TRF0206-SP EVM, a 3-port VNA is recommended which can generate single-ended and receive differential signals at the input and output ports of the EVM respectively.
  2. Before connecting the RF coax cables to the EVM, you must calibrate the VNA along with the cables using a calibration kit.
  3. Determine the frequency sweep and output power level from the VNA is set within the linear operating range of the TRF0206-SP devices. The resolution bandwidth (RBW) and dynamic range of the VNA can be adjusted to give the adequate sweep time for the measurement.
  4. Accounting for board trace losses at the input and output side of the device during gain measurements is important. Figure 3-2 gives typical input and output trace losses measured on the EVM.
