Introduction

The MLX73290-A combines a highly integrated Radio Frequency transceiver for long range, high speed

communication and a 3 dimensional low frequency interface (3DLF) for low power wake-up. This unique

combination makes the MLX73290-A suitable for applications requiring a very low power wake-up function

together with long range, high speed RF feedback.

The transceiver part allows for multi-channel operation including frequency hopping in the European bands

(433MHz and 868MHz) as well as in North America or Asia bands (315MHz or 915MHz). The output power,

frequency channel, modulation type and frequency deviation are programmable. Thanks to the high

frequency resolution and phase noise performance of its fractional-N PLL, the MLX73290-A is fit for narrow-

band operation. There are two selectable modulation schemes: binary on-off keying (OOK) and binary

frequency shift keying (FSK) as well as their Gaussian filtered versions. The low-IF receiver part comprises

fully digital demodulation and self-polling features together with channel scanning and built-in packet

recognition.

The 3DLF interface features an automatic and programmable wake-up algorithm together with an integrated

data decoder to receive the payload. Monitoring independently the RSSI information from the 3-axis LF front-

ends allows precise monitoring of the received LF field. Thanks to its internal rectifier, power management

and load modulator, the MLX73290-A is capable of battery-less LF RFID tag operation.
