Silicon Labs Si443x EZRadioPRO® Transceivers

Silicon Labs Si443x EZRadioPRO® Transceivers offer high integration, low cost, flexibility, low BOM, and easy design-in with sophisticated applications and enhanced parameters. These transceivers feature a continuous frequency coverage from 240MHz to 960MHz and output power up to +20dBm. The Si443x ISM band ICs include a wake-up timer, low battery detector, transmit and receive data FIFOs, power-on reset circuit, and general-purpose digital I/Os. Silicon Labs Si443x EZRadioPRO Transceiver ICs incorporate a high-performance ADC and digital modem, which perform demodulation, filtering and packet handling in the digital domain.

The Si4432 transceivers offer configurable output power from 11dBm to 20dBm and are ideal for frequency hopping systems where maximum range is desired. The Si4430/31 ICs have configurable output power from -8 to 13dBm. The Si4431 and Si4432 transceivers comply with FCC and ETSI requirements when used in any of the standard ISM Bands. A 30MHz crystal and supply bypass capacitors are the only necessary external components, making the devices ideal for high-volume production in applications where size and cost are important.
