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 Si4463/61/60 offers frequency coverage in all major bands. The Si4464 offers frequency coverage in bands not covered by Si4463/61/60. Typically, these are non-standard frequencies or licensed frequency 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 60 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 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 +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 Si4464/63 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 on the Silicon Labs web site.
