Description
Silicon Laboratories' Si446x devices are high-performance, low-current
trraadniossceaivreerspacrotvoefrinthgethEeZsRuabd-iGoPHRzOfr_®eqfuaemniclyy,
bands
which
from 142 to 1050 MHz. The
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.
