In a previous project with an RF power amplifier layout, there is a bias tee in the design that is used to provide DC power to the amplifier while also allowing RF power to propagate towards the output SMA connector. It is a 2-input, 1-output device that uses reactive elements to provide a power flow along different directions. To perform a Power Integrity analysis in Altium, the engineer first creates a hierarchical network of the entire power delivery system, identifying each power and return net, the sources and loads, as well as any series elements present in each section of the power network. Once the network and configuration settings have been defined, the Power Analyzer can examine the entire network.RF bias tees are used to separate DC and AC power along an interconnect. With results presented in both visual and tabular form, the engineer can use this feedback and quickly adjust the track widths, copper thicknesses, and via properties to ensure they achieve the integrity of DC power delivery required for their design. Rather than relying on simple cross-sectional area calculations to determine the current carrying capacity of the power network, the Power Analyzer first accurately models the copper structures, and then calculates the power delivery voltages and currents across the PCB. Generate an HTML report of the analysis simulation results.Examine the voltage, current density, and via current at any location on the board.Visualize the voltage and current density distribution and identify hotspots in the PCB editor.Calculate multi-network and return path interactions.Identify and resolve DC voltage and current density issues.Altium Designer supports DC analysis of a power delivery network using the Power Analyzer by Keysight, enabled by Keysight Technologies.ĭC Power Integrity analysis helps the engineer answers critical design questions, including: Power Integrity analysis, also called Power Delivery Network (PDN) analysis, can be performed in both the DC and the AC domains. To deliver today's high-performance products, engineers must evaluate their designs to detect and resolve any potential signal integrity (SI) and power integrity (PI) issues during the design stage.
