Abstract
A PIN diode attenuator with an average of 0.25°/dB phaseshift between 2.5 GHz and 5.3 GHz has been modelled and constructed. In particular the attenuator has similar phase at 0 dB and 12 dB of attenuation to within 0.5° over most of the band. The input match is better than 10 dB over the attenuation range of 0 to 10 dB
