Microwave microstrip attenuators for GaAs monolithic integrated circuits

Fixed attenuation microstrip attenuators calculations and T-attenuators with thin-film cruciform resistor prototypes experiments are represented. In the frequency range from 0 to 40 GHz T-attenuator attenuation irregularity is no more than 0.1 dB at 6 and 3 dB. Calculations were made considering the device as a combination of microstrip lines with parasitic parameters. L-2L de-embedding technique was used for experiment analysis.
