Description

Silicon Labs Si4362 devices are high-performance, low-current receivers covering the sub-GHz frequency bands from 142 to 1050 MHz. The radios are part of the EZRadioPRO? family, which includes a complete line of transmitters, receivers, and transceivers covering a wide range of applications. All parts offer outstanding sensitivity of –129 dBm while achieving extremely low active and standby current consumption. The 69 dB adjacent channel selectivity with 12.5 kHz channel spacing ensures robust receive operation in harsh RF conditions, which is particularly important for narrowband operation. RX current of 10 mA coupled with extremely low standby current and fast wake times ensure extended battery life in the most demanding applications.
