22 Citations | In addition, the applied strain can be tuned by changing the dimensions of the amplifier structure. |
19 Citations | In a uniform magnetic field, the instability exhibits an exceedingly narrow bandwidth, 2.5 MHz, which would be a great disadvantage in any practical application as an amplifier. |
Bifurcation loci provide instability contours versus practical design parameters and can be used to evaluate the impact of the instability on the overall amplifier performance and to stabilize the amplifier. | |
4 Citations | Gain saturation is strong in any efficient amplifier and we show how it can be exploited to raise instability thresholds be a factor of two or more while staying below the stimulated Brillouin threshold. |
A detailed study of these nonlinear shifts reveals several ways to reduce these new sources of frequency instability. | |
01 Jan 2005 12 Citations | Results show that both methods, if properly tuned, are effective techniques to reduce torsional oscillations and are robust to parameter variations. |
35 Citations | Under high powers and low inversion (high amplifier saturation) the thermal effects dominate the instability behavior. |

What are the disadvantages of using a double tuned amplifier?5 answersA double tuned amplifier has several disadvantages. It has poor selectivity, meaning it is not able to effectively filter out unwanted frequencies. Additionally, it has poor bandwidth, which limits the range of frequencies it can amplify. Another disadvantage is the greater power loss associated with a double tuned amplifier. However, when a double tuned amplifier is constructed by cascading two stages, the frequency bandwidth can be enlarged, resulting in improved performance. Despite these disadvantages, a double tuned amplifier can be beneficial in certain applications, such as in the IF amplifier of a receiver.
