Abstract :
The aim of the paper is to analyse and design variable attenuators equipped with ROV 211 chip PIN diodes. Nonlinear effects in such shunt PIN diode attenuators´ are analysed, too. The attenuators are manufactured as hybrid microwave integrated circuits on soft microwave substrate. Insertion losses less than 2 dB and a dynamic range of 27 dB for two octave bandwidth were obtained
