Relative operating bandwidth of quarter-wave transformer¶
The relative operating bandwidth of a quarter-wave transformer depends on the reflection coefficient, the surge impendance of the transmission line to which the transformer is connected and the load resistance.
- relative_bandwidth¶
Relative operating bandwidth is the ratio of the bandwidth to the center frequency.
