The MLX73290-M from Melexis is a multi-channel transceiver chip that operates from 300 MHz to 930 MHz. The transceiver delivers two RF channels, each with a programmable RF power transmitter and a highly sensitive RF receiver. It is fully programmable via its serial peripheral interface (SPI). It provides an output power from -20dBm to 13dBm with a receiver sensitivity can attain -120 dBm in a 15 kHz bandwidth. This transceiver is very flexible due to the high degree of programmability. 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. The MLX73290-M is ideal for sub-GHz wireless applications like home/building automation, tire pressure monitoring (TPMS), automatic meter reading (AMR), alarm systems, passive keyless entry (PKE), medical diagnostics and telemetry.
