The Si4438 is targeted at the Chinese smart meter market and is especially suited for electric meters. This device is footprint- and pin-compatible with the Si446x radios, which provide industry-leading performance for worldwide sub-GHz applications. 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 124 dBm while achieving extremely low active and standby current consumption. The 58 dB adjacent channel selectivity with 12.5 kHz channel spacing ensures robust receive operation in harsh RF conditions. The Si4438 offers exceptional output power of up to +20 dBm with outstanding TX efficiency. The high output power and sensitivity results in an industry-leading link budget of 144 dB allowing extended ranges and highly robust communication links.
