Analog Devices' ADISimRF v1.7 Released

Analog Devices just announced the release of the latest version of their ADISimRF applet for calculating cascaded RF component parameters. It takes typical input values for up to 15 stages and returns typical cascaded values at the output. As I do with any such program, I compared its results with those of my RF Cascade Workbook (RFCW) spreadsheet. The numbers agree as expected since both use pretty much the same set of well-established textbook formulas. One difference in the two programs is that ADISimRF appears to use the standard IP3 (3rd-order intercept point) cascade formula for calculating P1dB (1 dB compression point), whereas RFCW uses Psat (saturated power) instead since the P1dB formula is only an approximation of widely varying nonlinear response and might lead to a false sense of security. RFCW's Psat calculated values simply test what the output power level for a device would be... http://www.rfcafe.com/miscellany/press-releases/2013/adisimrf-vs-rfcw.htm
