Complete Circuit Design Spanning From DC To Microwave Frequencies

ntroduction

RF and microwave circuit designers choose Microwave Office software because of its complete range of powerful circuit design capabilities, from design capture, to harmonic balance and time-domain simulation, to layout, synthesis, and optimization, and even electromagnetic analysis and post-layout verification.

The Microwave Office design environment is well suited for higher-frequency designs, and, when combined with National Instrument’s Multisim circuit simulation software through AWR Connected, low-frequency circuit functionalities are added for an even more complete circuit design flow (DC up through microwave/RF). Moreover, NI’s Ultiboard printed circuit board layout software is capable of integrating high-frequency circuit layouts with Multisim, enabling designers to rapidly create a layout of a complete prototype, add mechanical and graphical shapes to the design, create 3D views of the final design, and export standard Gerber files, as well as other formats, for fabrication.

With the flexible routing capabilities of Ultiboard, all the particular details of the RF circuit affecting the frequency response are preserved (such as the transmission line bends, matching networks, and ground vias), while all the complementary low-frequency circuits are quickly routed around it.
