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.
