描述CC1190 is a cost-effective and high-performance RF Front End for low-power and low-voltage wireless applications at 850 -950 MHz. CC1190 is a range extender for the sub-1 GHz low-power RF transceivers, transmitters, and System-on-Chip devices from Texas Instruments.CC1190 integrates a power amplifier (PA), a low-noise amplifier (LNA), switches, and RF matching for thedesign of a high-performance wireless systems. CC1190 increases the link budget by providing a power amplifier for increased output power, and an LNA with low noise figure for improved receiver sensitivity.CC1190 provides an efficient and easy-to-use range extender in a compact 4-mm × 4-mm QFN-16 package.特性Seamless Interface to Sub-1 GHz Low Power RF Devices from Texas Instruments Up to 27 dBm (0.5 W) Output Power 6 dB Typical Sensitivity Improvement with CC11xx and CC430 Few External ComponentsIntegrated PAIntegrated LNAIntegrated SwitchesIntegrated Matching NetworkIntegrated InductorsDigital Control of LNA and PA Gain by HGM Pin 50-nA in Power Down (LNA_EN = PA_EN = 0)High Transmit Power Efficiency PAE = 50% at 26 dBm Output PowerLow Receive Current Consumption3 mA for High Gain Mode26 μA for Low Gain Mode2.9 dB LNA Noise Figure, Including Switch and External Antenna MatchRoHS Compliant 4-mm × 4-mm QFN-16 Package2 V to 3.7 V OperationAPPLICATIONS 850- 950 MHz ISM Bands Wireless Systems Wireless Sensor NetworksWireless Industrial SystemsIEEE 802.15.4 SystemsWireless Consumer SystemsWireless Metering (AMR/AMI) SystemsSmart Grid Wireless Networks
