AT86RF211 Transceiver Radio Applications Application Requirements
Components around transceivers classified into four families: filtering out-of-band high-level jamming such pagers' Base Stations portable phones. These most expensive parts (e.g. SAW). filtering protect against other users bands. They cheap multisource. Filtering decoupling power supplies. These always very cheap (resistors, capacitors). passive components antenna matching, loop filtering.
SmartRF Series Application Note
Thanks AT86RF211's very high level integration (incuding inductor varactor), critical components have added outside chip. Such super-heterodyne device very flexible allows achieve cost standard applications, well high performances (immunity, selectivity, etc.) industrial systems: external filters removed/chosen according performance requirements. There wide variety filters, with various bandwidths costs (simpler filters with discrete components also possible) meet requirement. same layout used several applications (unique platform). This allows adapt performance requirements with minimal design efforts resulting very short time-to-market.

Multi-sourcing
AT86RF211 fully integrated component that does require external critical component. consequence, possible several different sources them. components mounted development tools/reference designs described different BOMs. this annex give examples other suppliers. Please note that there NEVER TRUE second source component! instance, another inductor will have different quality factor. consequence, switching from supplier another require slight adaptation nominal values.
