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.
