Operation Of Microwave Precision Fixed Attenuator Dice Up To 40 GHz

The YAT-D-Series MMIC attenuator dice from Mini-Circuits are fixed-value, absorptive attenuators designed with low thermal resistance, very wideband operation, and nominal attenuation values of 0 to 10 dB (in 1 dB steps). The attenuator's performance is characterized by a continuous ground plane underneath the entire die, that when modified can achieve excellent return loss and attenuation flatness up to 40 GHz. This application note demonstrates a method of expanding the YAT-3- D+ MMIC attenuator's usability for applications up to 40 GHz. Download the full article for more information.
