10 Insertion Loss Calibration

The TX power levels and RX sensitivity numbers quoted in the data sheet are at the device RF pin. Additional losses due to onboard filter, PCB trace, connectors, and cables used to connect to the external RF equipment should be accounted for separately by adding their insertion losses.

On the TI EVMs, the onboard filter insertion loss is typically 1 dB (maximum of 1.35 dB); the PCB trace plus RF connector loss is approximately 0.4 dB. These losses must be accounted for while evaluating the performance. If you have a different filter or a different trace on your PCB, you must measure the insertion loss separately. The insertion loss of the cable used to connect the EVM to the external equipment can be measured using a network analyzer.
