Description  
Patents pending  
Silicon Laboratories' Si446x devices are high-performance, low-current  
transceivers 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. A  
high level of integration including support for IEEE 802.15.4 features enables  
standards based sub GHz networking solutions. All parts offer outstanding  
sensitivity of –133 dBm while achieving extremely low active and standby current  
consumption. The Si4468/7 offers frequency coverage in all major bands. The  
Si446x 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 69 dB adjacent channel selectivity with 12.5 kHz channel  
spacing ensures robust receive operation in harsh RF conditions, which is  
particularly important for narrow band operation. The Si4468 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 155 dB allowing  
extended ranges and highly robust communication links. The Si4467 active mode  
TX current consumption of 18 mA at +10 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 Si4468 can achieve up to +27 dBm  
output power with built-in ramping control of a low-cost external FET. The devices  
can meet worldwide regulatory standards: FCC, ETSI, and ARIB. All devices are  
designed to be compliant with 802.15.4g and WMBus smart metering standards.  
The devices are highly flexible and can be configured via the Wireless  
Development Suite (WDS) available at www.silabs.com.
