Addressing the sub-GHz ISM bands from 300 MHz through to 960 MHz, the MLX73290-M from Melexis delivers two RF channels, each with a programmable RF power transmitter and a highly sensitive RF receiver.
Fully programmable via its serial peripheral interface (SPI), it is highly suited to applications like home/building automation, tyre pressure monitoring (TPMS), automatic meter reading (AMR), alarm systems, passive keyless entry (PKE), medical diagnostics and telemetry.
The chip’s output power level ranges from -20 dBm to 13 dBm while its receiver sensitivity can attain -120 dBm in a 15 kHz bandwidth. With a maximum data rate of 250 Kbps, it is also capable of handling heightened data throughputs. On-off keying (OOK), binary frequency shift keying (FSK), minimum shift keying (MSK), Gaussian minimum shift keying (GMSK) and Gaussian frequency shift keying (GFSK) modulation schemes are supported.
Thanks to the high degree of programmability, engineers employing this IC are presented with plenty of scope when it comes to configuring and implementing an RF front-end. A wide variety of different RF parameters can be adjusted (number of channels, frequency resolution, output, frequency deviation, etc.) in order to satisfy specific application criteria.
Two RF power detectors provide augmentation of radiated power performance during transmission. An energy harvesting interface allows battery-less power supply by using a solar cell in combination with a supercapacitor. Evaluation boards and software tools are also available.
