Product Overview

SI4055-C2A-GM is a EZRadio Transmitter. It combines plug-and-play simplicity with the flexibility needed to handle a wide variety of applications. The compact 3x3 mm package size combined with a low external BOM count makes the Si4055 both space efficient and cost effective. The +13dBm output power and excellent sensitivity of -116dBm allows for a longer operating range, while the low current consumption of 18mA TX (at 10dBm), 10mA RX and 40nA standby, provides for superior battery life. By fully integrating all components from the antenna to the GPIO or SPI interface to the MCU, the Si4055 makes it easy to realize this performance in an application. Design simplicity is further exemplified in the Wireless Development Suite (WDS) user interface software. WDS provides simplified programming options for a broad range of applications in an easy-to-use format that results in faster and lower risk development.
