3 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-todigital

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 powerdown

feature is also available for power savings.
