Staggered tuning

英语百科

Staggered tuning

A typical multi-stage tuned amplifier.  The amplifier is synchronously tuned if all LC-circuits are tuned at the same frequency, which occurs if all the products Ck * Lk are equal. In staggered tuning, the products Ck * Lk are generally different in each stage.
Plot showing the reduction of bandwidth caused by synchronous tuning with increasing number of stages, n.  The Q of each stage is 10 in this example.
Comparison of synchronous and staggered tuning responses
Generic multi-stage tuned amplifier

Staggered tuning is a technique used in the design of multi-stage tuned amplifiers whereby each stage is tuned to a slightly different frequency. In comparison to synchronous tuning (where each stage is tuned identically) it produces a wider bandwidth at the expense of reduced gain. It also produces a sharper transition from the passband to the stopband. Both staggered tuning and synchronous tuning circuits are easier to tune and manufacture than many other filter types.
