描述 Description

The TRF1213 is a very high performance, radio frequency (RF) amplifier optimized for RF applications. This device is excellent for ac-coupled applications that require a single-ended to differential conversion when driving an RF sampling analog-to-digital converter (ADC) such as the high performance AFE7950 or ADC12DJ5200RF. The device combines the functionality of a wide-band gain block and a wide-band passive balun. The on-chip matching components simplify printed circuit board (PCB) implementation and provide the highest performance over the usable bandwidth. The device is fabricated in Texas Instruments’ advanced complementary BiCMOS process and is available in a space-saving, WQFN-FCRLF package.

The TRF1213 operates on a single-rail supply and consumes about 174mA of active current. A power-down feature is also available for power savings.
