Description

Silicon Laboratories' Si4438 is

high-performance, low-current

Patents pending

transceivers covering the sub-GHz frequency bands from 425 to

525 MHz. 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.
