Melexis programmable multi-channel radio frequency transceiver aims at low power SUB-GHz applications

Mai Mai Cixis Company launched MLX73290-M. The multi-channel RF transceiver IC utilizes the company's long-term technical expertise in low power wireless implementation. The product can meet the SUB-GHz ISM band from 300 MHz until 960 MHz, two RF channels, each channel with a programmable RF power transmitter and a high sensitivity RF receiver. It can be fully programmable through its serial peripheral interface (SPI). This IC is ideal for SUB-GHz wireless applications, such as homes / building automation, tire pressure monitoring (TPMS), automatic meter reading (AMR), alarm system, passive keyless entry (PKE), medical diagnosis and telemetry. Its output power level ranges from -20 dBm to 13dBm, and its receiving sensitivity can reach -120 dBm within a bandwidth of 15 kHz. The transceiver maximum data rate is 250 kbps, so it is also possible to handle higher data throughput. Due to the high programming level, the front end of the RF is configured and implemented, the engineer will have a lot of room for this chip. Users can regulate a wide variety of different RF parameters (channel number, frequency resolution, output, frequency deviation, etc.) to meet specific application criteria. This chip supports the key control (OOK), binary movement (FSK), minimum frequency shift keying (MSK), Gaussi minimum frequency shift keying (GMSK), and Gaussian frequency shift key (GFSK) and other modulation schemes. Two RF power detectors provide radiation power performance during transmission. The energy acquisition interface allows the battery to be powered by using solar cells and supercapacitors. This highlights its value in the remote location of the lack of power lines. In addition, it provides an evaluation board and software tool. The MLX73290-M is supplied with 5mm x 5mm 32 pin QFN package. Its operating temperature range is -40 ° C to 105 ° C.
