NI (formerly AWR Corp) of El Segundo, CA, USA says that India-based RF/microwave module and sub-system maker Astra Microwave Products Ltd (AMPL) has designed an S-band gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) digital phase shifter as well as a digital attenuator for active phased-array radars using NI AWR Design Environment software.
NI says that its Microwave Office software gave the designers an advantage by speeding up the layout process, as any changes made in the layout were automatically updated in the schematic with updated simulation results, while AXIEM provided the designers with the ability to EM simulate and optimize the entire structure and avoid layout coupling.
"NI AWR software has improved the AMPL MMIC design flow and has reduced simulation times while at the same time providing better accuracy in simulation results," comment assistant manager K. Suman Reddy and engineer M. Laxmi at Astra. "It has given us an incredible advantage by speeding up the entire layout process," they add.
