Be Selective

Filters play a critical role in mitigating signal interference and allowing coexistence between bands in today's spectrally crowded mobile environment. Designing form-factor filter solutions with low passband insertion loss and sufficient stopband rejection requires a design flow that supports filter synthesis through physical realization and verification. The Cadence® AWR Design Environment® platform addresses all stages and types of filter development, from lumped-element or distributed filters to more complex multiplexed, high-power, and high-Q cavity filters.

Key Benefits

Fast

Accelerate design starts with powerful synthesis of lumped and distributed filter types

Reliable

Accurately predict the response of distributed and cavity-type filters with planar method-of-moments (MoM) and 3D finite-element method (FEM) electromagnetic (EM) analysis

Productive

Directly import synthesized designs into Cadence® AWR Microwave Office® circuit design software for further refinement, optimization, EM verification, and physical design

Solution Highlights

Design Starts

Filter designs start with specification of the required frequency response, physical constraints, and likely technology for implementation based on the target application, which drive cost and form factor considerations. Given a target technology and filter type, filter synthesis determines the initial physical dimensions prior to design layout, optimization, and verification stages. 

Model Support

Libraries of surface-mount technology (SMT) vendor components and distributed transmission-line elements allow designers to build and simulate filters for physical realization through a schematic editor fully synchronized to a layout editor. Parameterized EM subcircuits can be used for novel structures to develop filters and resonators used as custom building blocks.

Simulation

Linear frequency domain analysis allows designers to simulate broadband filter responses including in- and out-of-band rejection, return and insertion losses. Designers rely on circuit/EM co-simulation to provide embedded parasitic extraction and design verification, along with RF-aware circuit simulation and frequency-dependent transmission-line models. Prior to manufacture, component performance can be verified through planar or 3DEM analysis.

Options

Optional features can be added to AWR RF/microwave design software to enhance engineering productivity, product performance, and speed time to market. The AWR iFilter™ synthesis wizard within AWR software accelerates design starts, enabling engineers to create lumped-element and distributed filters based on user-defined filter responses. The descriptive interface guides users through realizable filters and options and supports low-pass, high-pass, bandpass, and bandstop filters. From accelerating the initial RF design effort with filter and network synthesis tools to significantly reducing simulation and optimization run times with parallel, distributed computing, these options ensure your organization gets the most out of its RF EDA investment and engineering resources.
