Abstract
A pin diode variable attenuator featuring decouping values higher than those achievable using the technique used so far, is described. This result has been achieved by implementing the line sections which the pin diodes are connected to with a characteristic impedance different than the characteristic impedance input and output to/from the attenuator.
