The TRF1208 is a 10MHz to 11GHz, 3dB bandwidth, single-ended to differential amplifier
The TRF1208 is an AD7940BRJZ-REEL7 high performance RF amplifier optimized for radio frequency (RF) applications. This device is ideal for AC-coupled applications that require single-ended to differential conversion when driving analog-to-digital converters (ADCs) such as the high-performance ADC12DJ5200RF. On-chip matching components simplify printed circuit board (PCB) implementation and provide the highest performance within the available bandwidth. The device is fabricated on Texas Instruments' advanced complementary BiCMOS process in a space-saving WQFN-FCRLF package.
It operates from a single rail supply and consumes approximately 138 mA of active current. The power-off function can also be used to save power.
