AbstractPresent bandwidth limiters use a six-pole bessel filter approach to limit the power bandwidth of the transmitter to IRIG-106-86 requirements. However, the filter must be reconfigured if frequency changes in the data stream are desired for system requirement purposes, eg. adding encryption. The circuits set forth herein will provide for frequency change of the data stream while also providing a power increase by reducing the out of band power.
