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.

Silicon Labs and RFMD have collaborated to jointly produce a reference design that features the Silicon labs EZRadioPRO Si4464/63 sub GHz ISM band radio transceivers and the RFMD® RF6569 front end module (FEM) optimized for smart grid automatic meter reading (AMR) applications that want to economically boost output power to +30 dBm.
The 4463-TCE30E915R-EK RF test card features the EZRadioPRO Si4463 transceiver operating at 915 MHz and utilizes the RFMD RF6569 FEM which includes an integrated PA, TX harmonic filtering, SPDT switch and RX balun.
Following the reference design, a customer can successfully complete a design based upon both the EZRadioPRO Si4464 or Si4463 transceiver and the RFMD RF6569 FEM operating in the 868 MHz or 902 to 928 MHz ISM bands.
