Tools & Simulations

S-Parameter 1

ADIsimRF

ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

ADIsimPLL™

ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.

Product Details

AD8309-EVALZ is a full featured, 4-layer, FR4-based evaluation board designed to allow easy evaluation of all features of the AD8309. RF input, limiter output and VLOG output SMA connections with single ended setups are featured. There is an option of full differential signaling on the RF input and limiter output at card edge if the user desires. Access to the +5V/16 mA supply is achieved with clip leads to the Vs and COM testpoints; it has a range from +2.7 to +6.5V.
