7.2.1 RF DAC Buffer Amplifier

A common application of the TRF0108-SEP is to function as a buffer amplifier for an RF DAC, such as the DAC39RF10-SEP or AFE7950-SEP, which have differential outputs. Conventionally, passive baluns are used to interface with RF DACs as a result of the low-availability of high-bandwidth, linear amplifiers. The TRF0108-SEP is a differential-to-single-ended amplifier that has excellent gain and phase imbalance, input and output return loss, and exceeds the performance of bulky and expensive passive baluns for DAC buffer applications. The TRF0108-SEP integrates the functionality of a wide-band passive balun and gain-block in a single 2mm x 2mm package, reducing PCB area for high channel count RF systems.

The following figure shows the schematic where the TRF0108-SEP is used as a DAC buffer amplifier.
