The TRF1208 is a very high-performance amplifier optimized for radio frequency (RF) and intermediate frequency (IF) with signal bandwidths up to 11 GHz. The low frequency response is limited only by the ac‑coupling capacitor on the PCB. The device is designed for ac-coupled applications that require a single-ended to differential conversion when driving an analog-to-digital converter (ADC). The device has a two-stage architecture and provides approximately 16 dB of gain for the TRF1208 and approximately 10 dB of gain for TRF1208B when configured for single-ended inputs driven from a 50-Ω source. This device also works as a differential-to-single-ended amplifier to act as a DAC buffer.

This device does not require any pullup or pulldown components on the PCB, and thereby simplifies the layout and provides the highest performance over the entire bandwidth.

The input and output are ac coupled. The TRF1208 is powered with 3.3‑V supply. A power-down feature is also available.
