3.1.2 Noise Figure Test Setup

TRF0108SP-EVM TRF0108SEP-EVM Noise Figure Test Setup Figure 3-3 Noise Figure Test Setup

Use the following guidelines for noise figure (NF) measurement:

  1. As shown in Figure 3-3, the traditional Y-factor method can be used for the NF measurement using a noise diode and a spectrum analyzer (or a noise figure analyzer).
  2. For accurate NF measurement, account for RF cable losses to the EVM and for any external attenuators used in the setup
  3. Also, onboard losses of the input traces at the device input pins must be factored into the NF measurement
  4. If the loss after the device output is significant (greater than about 5dB) then factor the output loss into the NF measurement. Use the Friis equation to calculate the NF of the device from the total measured NF.
