EVB90121

The EVB90121 is an assembled module that allows to evaluate the advantages of the MLX90121 13MHz transceiver IC and to facilitate the development of RFID applications.

The EVB90121 board voltage is supplied by a jack connector from 6 to 9 Volts DC. The internal power supply of the board can be chosen between 3 Volts and 5 Volts DC by putting the corresponding jumper up or down. A suppression choke reduces the supply noise.

The EVB90121 matching network can be adjusted through CV1 capacitor and thus can be optimized to transmit full electromagnetic power up to 200mWatt to a 50-ohm load antenna connected on a SMA connector.

All digital inputs/outputs from the MLX90121 are connected to a standard 10 pins connector. This allows easy connection to a microcontroller.
