Abstract :
Narrowband elliptic filters suffer high inductance spread which makes them impractical above 100 MHz. A description is given of a sequence of transformation that leads to a nonladder realization. All critical inductors can be assigned a common optimum value, which is independent of the bandwidth. The filter response is insensitive to the Q of the remaining coils, which have lower inductance values. Some other practical design matters are discussed
