Noise Figure Measurement - A Practical Approach
4. Two-port Network Characterization:
A two-port network can be represented as below:
The noise in a circuit can be characterized by the following parameters:
- Gain, G
- Bandwidth, B
- Noise Figure, F
Assuming that the input is driven by noise temperature at T, the output noise of the two-port network is given by kTGBF, where G is the gain, B is the bandwidth, and F is the Noise figure of the circuit under consideration.
