AS3992-DK MICRO: UHF 900MHz RFID Reader

The MICRO UHF RFID Reader reference design from ams is a Low Cost EPC Class 1 Gen 2 compliant UHF RFID Reader system. Leveraging the AS399x family of UHF RFID Reader IC’s, provides close to the industry’s lowest BOM cost, best in class power consumption with the least amount of complexity.

Second only to ams PICO design the low reader BOM enables UHF RFID markets that have previously been out of reach due to cost restraints. With regards to overall cost vs performance the MICRO UHF RFID reference design is unmatched in the industry.

With an external PA delivering up to 23 dBm, it is ideally suited for those applications that have similar cost constraints but require that extra power.

The MICRO reference design comes in two parts namely the analogue (RF) and digital (controller) parts. The user can separate the two boards to fully prove out their own RF and digital parts. With this set up it also means the user can evaluate the suitability of RFID in their current system.

The RF portion is designed such that it can be easily connected to a host micro via SPI. The high level of integration found on the AS399x UHF RFID Reader IC’s allows for minimal code loading and quick implementation.

The reference designs come with free, fully portable code and all gerbers and schematics. This allows for a quick, trouble free design in.
