The SI4461-C2A-GM is a high-performance Low-current Transceiver covering the sub-GHz frequency bands from 142 to 1050MHz. 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 -129dBm while achieving extremely low active and standby current consumption. The Si4460 offers frequency coverage in all major bands. The Si446x includes optimal phase noise, blocking and selectivity performance for narrow band and wireless MBus licensed band applications, such as FCC Part90 and 169MHz wireless Mbus. The 69dB adjacent channel selectivity with 12.5kHz channel spacing ensures robust receive operation in harsh RF conditions, which is particularly important for narrow band operation. The Si4463 offers exceptional output power of up to +20dBm with outstanding TX efficiency.
