Si446x主要特性:
18mA TX at +10 dBm (Si4460)
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.
