1. Operational description

The RWTRSS10433B-40 is “Stamp” that transmit in 433.92Mhz .

The Transceiver Si4432 is by Silicon Laboratories’ highly integrated, single chip wireless ISM. It
includes a complete line of transmitters, receivers, and transceivers allowing the RF system
designer to choose the optimal wireless part for their application.

The Si4432 offers advanced radio features including continuous frequency coverage from 240–
930 MHz. The Si4432’s high level of integration offers reduced BOM cost while simplifying the

overall system design. Additional system features such as an automatic wake-up timer, low
battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection
reduce overall current consumption and allow the use of lower-cost system MCUs. An
integrated temperature sensor, general purpose ADC, poweron- reset (POR), and GPIOs further
reduce overall system cost and size.

The Si4432’s digital receive architecture features a high-performance ADC and DSP based
modem which performs demodulation, filtering, and packet handling for increased flexibility and
performance. This digital architecture simplifies system design while allowing for the use of
lower-end MCUs. The direct digital transmit modulation and automatic PA power ramping
ensure precise transmit modulation and reduced spectral spreading ensuring compliance with
FCC and ETSI regulations.
