Si4455 EZRadio® Transceivers

Silicon Labs Si4455 EZRadio^® Transceivers are easy-to-use, low-current, and sub-GHz devices. These transceivers combine plug-and-play simplicity with the flexibility needed to handle various applications. Silicon Labs Si4455 transceivers come in a compact 3mm x 3mm package combined with a low external BOM count, making the devices both space-efficient and cost-effective. The 13dBm output power and excellent sensitivity of -116dBm allow for a longer operating range. The low current consumption of 18mA TX (at 10dBm), 10mA RX, and 50nA standby provides for superior battery life.
