A filter (102) with an adjustable shunt zero. The filter (102) has a predetermined passband and stopband, and an input (104) and an output (106), and a variable reactance element (108) for adjusting the stopband frequency of maximum attenuation, also defined as a shunt zero, coupled to at least one of the input (104) and the output (106) of the filter (102), whereby the shunt zero is adjustable over a range of frequencies.
