*1 – Data is based upon a 5-section filter. Upper limit is ~6% bandwidth and 8 sections.
*2 – Standard rejection frequencies (F RL and F RH ) are calculated at center frequency ± (1.5 x bandwidth in GHz).
*3 – Please consult Millitech for further information.
NOTE: Other bandwidth percentages are available upon request. See series FIB for other bandwidth
requirements and options, or contact Millitech for more information.
