WebAug 29, 2024 · It can be seen that the gain flatness is better, but the input reflection coefficient is poor, and an additional matching structure needs to be added. 3.4 Design Matching Network Based on Equal VSWR Circle. In this broadband low-noise amplifier design, an equal VSWR circle is added to the conventional equal noise figure circle and … WebGain flatness indicates the variation of an amplifier's gain characteristic over the full frequency response range at a given temperature expressed in ±dB. The value is obtained by taking the difference between maximum and minimum gain, and dividing it by 2. Gain (forward gain, G) for RF amplifiers is the ratio of output power to input power,

Weboptimum performance. Once the gain flatness specification is set, the engineer can derive the required 3 dB bandwidth for the system based on the frequency response type and order of the system. The ratio between the cutoff frequency and the minimum video frequency corresponding to 0.1 dB and 0.5 dB gain flatness respectively is listed in
WebGain flatness should be +/- 1.5 dB across the entire band. Ripple is another specification closely related to band flatness. Ripple is the peak-to-peak variation of the signal over a narrow portion of the band, say 10 MHz. Good ripple specs are in the order of +/- 0.1 dB over any 10 MHz. 9.
