Silicon Laboratories’ Si4012 is a fully integrated crystal-less CMOS high-data rate
RF transmitter designed for the sub-GHz ISM band. This chip is optimized for
battery powered applications requiring low standby currents and high output
transmit power.
The device offers advanced radio features including continuous frequency
coverage from 27–960 MHz, adjustable output power of up to +10 dBm, and data
rates up to 100 kbaud in FSK mode. The Si4012’s high level of integration offers
reduced BOM cost while simplifying the overall system design.
