double-tuned amplifier









































a double-tuned amplifier is a tuned amplifier with transformer coupling between the amplifier stages in which the inductances of both the primary and secondary windings are tuned separately with a capacitor across each. the scheme results in a wider bandwidth and steeper skirts than a single tuned circuit would achieve.
double-tuned amplifier
cascading multiple stages of double-tuned amplifiers results in a reduction of the bandwidth of the overall amplifier. two stages of double-tuned amplifier have 80% of the bandwidth of a single stage. an alternative to double tuning that avoids this loss of bandwidth is staggered tuning. stagger-tuned amplifiers can be designed to a prescribed bandwidth that is greater than the bandwidth of any single stage. however, staggered tuning requires more stages and has lower gain than double tuning.
