Description
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. All
parts offer outstanding sensitivity of –129 dBm while achieving extremely low
active and standby current consumption. The Si4463/61/60 offers frequency
coverage in all major bands. The Si446x includes optimal phase noise, blocking,
and selectivity performance for narrow band and wireless MBus 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 Si4463 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 +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 Si4463 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, wireless MBus, 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 on the
Silicon Labs website.
