Description  
Patents pending  
Silicon Laboratories' Si446x devices are high-performance, low-current  
transceivers covering the sub-GHz frequency bands from 119 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 –126 dBm while  
achieving extremely low active and standby current consumption. The Si4464  
offers continuous frequency coverage across the entire sub-GHz band from  
119–960 MHz with extremely fine frequency resolution. The Si4463 includes  
optimal phase noise, blocking, and selectivity performance for narrow band  
and licensed band applications, such as FCC Part90 and 169 MHz wireless  
Mbus. The 60 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. The Si4464/63 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 146 dB  
allowing extended ranges and highly robust communication links. The Si4460  
active mode TX current consumption of 18 mA at +11 dBm and RX current of  
10 mA coupled with extremely low standby current and fast wake times  
ensure extended battery life in the most demanding applications. The  
Si4464/63 can achieve up to +27 dBm output power with built-in ramping  
control of a low-cost external FET. The devices are compliant with all  
worldwide regulatory standards: FCC, ETSI, and ARIB. All devices are  
designed to be compliant with 802.15.4g and WMbus smart metering  
standards.
