The challenge was to design an EDGE/GSM power amplifier for a cellular handset. It was essential to accurately characterize the power amplifier’s circuit performance at the system level and to accurately predict adjacent channel power ratio (ACPR) measurements using modulated signals as opposed to traditional two-tone analysis. AWR’s Microwave Office® and Visual System Simulator (VSS) software were used for the design.
I was able to accurately characterize power amplifier circuit performance at the system level and accurately predict ACPR measurements using modulated signals as opposed to traditional two-tone analysis.
The ACPR measurements simulated with VSS agreed with laboratory measurements, and the VSS simulation ran approximately two times faster than the alternative solution.
The user environment, interactivity of the VSS system tool with the Microwave Office circuit tool, and the superior technical support.
