5-6 GHz band GaAs MMIC five bit digital attenuator

The results of design of the MMIC of five-bit microwave frequency attenuator are presented. The attenuator is executed on a crystal of gallium arsenide with dimensions 2.6 times 1.6 mm2 and provides in a strip of frequencies 5 - 6 GHz signal amplitude control in a band 0 - 31 dB with a step 1 dB and initial losses - 6 dB. Research of a channel resistance of the transistor made on two types of epitaxial structures is carried out.
