Covering all major bands, 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 Si4355 both space efficient and cost effective. Excellent sensitivity of 116 dBm allows for a longer operating range, while the low current consumption of 10 mA active and 50 nA standby, provides for superior battery life. By fully integrating all components from the antenna to the GPIO or SPI interfa...
