A bandwidth compensated switched bridged-tee attenuator having an attenuation state and a reference state. In order to cause the overall bit attenuation DELTA A to be frequency independent over a relatively wide range of frequencies, one or more additional switches are provided to cause the attenuation state to essentially track the frequency dependence of the reference state. Since the overall attenuation DELTA A is the difference between the attenuation in the attenuation state and the attenuation in the reference state, the overall attenuation DELTA A, is virtually frequency independent over a relatively wide range of frequencies.
