Si4464/63/61/60

HIGH-PERFORMANCE, LOW-CURRENT TRANSCEIVER

Features

Applications

Description

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.
