Questions & Answers
Q: What parameters are required to calculate the power gain, noise figure, and bandwidth of a parametric amplifier?
The parameters required are the ratio of output frequency to signal frequency, the figure of merit, the figure of merit figure, and the diode temperature.
Q: How is the power gain calculated?
The power gain is calculated using the formula: gain = (F0/FS) * (X/(1 + sqrt(1 + X))^2. Substituting the given values, the power gain is computed as 9.55.
Q: What is the formula for calculating the noise figure?
The noise figure is calculated using the formula: F = 1 + (2 * TD / T0) / (1 / (gamma * Q) + 1 / (gamma * Q)^2). Substituting the given values, the noise figure is computed as 1.
Q: How is the bandwidth calculated?
The bandwidth is calculated using the formula: BW = 2 * gamma * sqrt(A0/FS). Substituting the given values, the bandwidth is computed as 4.
