Features

Synthesize / Optimize / Realize 

  • iFilter - Accelerate design starts with this filter synthesis module within the NI AWR Design Environment, developed specifically for creating lumped-element and distributed filters based on user-defined filter responses. Supporting low-pass, high-pass, band-pass, and band-stop filters, the descriptive interface guides the user through realizable filters and options. 
  • Microwave Office - Coupled with iFilter, Microwave Office software enables RF engineers to quickly design filters, connect them directly to circuitry, and implement via automatic generation of schematics, result graphics, and tuning parameters/optimization goals.
  • AXIEM and Analyst™ - Perform electromagnetic verification for both planar filter structures as well as arbitrary 3D structures common to cavity filters with these EM technologies within NI AWR Design Environment.
