The SI4455-B1A-FM is an easy-to-use low current sub-GHz EZRadio® transceiver covering all major bands and it combines plug-and-play simplicity with the flexibility needed to handle a wide variety of applications. The 13dBm output power and excellent sensitivity of -116dBm allows for a longer operating range while the low current consumption of 18mA TX standby provides for superior battery life. By fully integrating all components from the antenna to the GPIO or SPI interface to the MCU, the transceiver makes realizing this performance in an application easy. Design simplicity is further exemplified in the wireless development suite (WDS) user interface module. This configuration module provides simplified programming options for a broad range of applications in an easy to use format that result in both a faster and lower risk development.
