AWR offers frequency planning wizard for determining spurious free bandwidths in communication system design
Whether developing satellite communication, cellular, or military radio links, RFP is an essential part of the design process in that it provides greater insight into unwanted signals or spurs generated in a specified bandwidth. As well as analyzing spurs generated by a lineup of mixers, RFP analyzes the entire RF lineup of common components (amplifiers, mixers, filters, etc.) found in radio communication links.
RFP excels as a frequency planning simulation tool in two ways. First, in addition to spur analysis, RFP gives engineers the first cut of cascaded measurements such as noise figure (NF), gain compression (P1dB), signal-to-noise-ratio (SNR) and third-order intermodulation (IM3), as well as spurious free dynamic range. Second, RFP is seamlessly integrated with AWR’s VSS communications system design software so that with a single mouse click the RF link constructed in RFP is automatically translated to a VSS system diagram. VSS can then be used to account for mismatch between components, account for noise at image frequency, and run yield analysis and optimization. Engineers then have a choice of modulated signals and can perform, for example, error vector magnitude (EVM), adjacent channel power ratio (ACPR), and bit error rate (BER) measurements.
