Analog Devices announced new releases of two popular RF design tools. The ADIsimRF tool is the software accompaniment to the company’s portfolio of RF-to-digital functional blocks, allowing engineers to model RF signal chains using devices from across its RF IC portfolio. The ADIsimRF Rev. 1.5 enhancements include more visibility into signal levels within the signal chain, the ability to set RMS and peak power warning thresholds, and calculators for measuring inter-stage power loss.
ADIsimRF provides calculations for the most important parameters within an RF signal chain, including cascaded gain, noise figure, IP3, P1dB and total power consumption. It also contains embedded data from many of AD’s RF ICs, which designers can easily access using pull-down menus. Device tables assist in component selection.
ADIsimPLL Version 3.4 development software has been upgraded to support new products in AD’s PLL portfolio, the ADF4351 PLL for base station and general-purpose applications and the ADRF6850 integrated broadband receiver for satellite applications. The design tool is a comprehensive PLL synthesiser design and simulation tool. All key non-linear effects that can impact PLL performance can be simulated, including phase noise, fractional-N spurs and anti-backlash pulse.
