Two downloadable software tools from Analog Devices are intended to aid in RF systems design. The ADIsimRF design tool calculates a variety of parameters within an RF system including cascaded gain, noise figure, and power consumption. ADIsimPLL Version 3.1 development software assists users in evaluating, designing, and troubleshooting RF systems. The design tool provides calculations for parameters within the RF signal chain, including cascaded gain, noise figure, IP3, P1dB, and total power consumption. Designers can vary the number of stages up to a maximum of 15.
