6.1 Overview

The TRF0208-SEP is a very high-performance amplifier optimized for radio frequency (RF) and intermediate frequency (IF) with signal bandwidths up to 11GHz. 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 low frequency response is limited only by the ac‑coupling capacitor on the PCB. If the lowest signal frequency is 10MHz, use 100nF ac-coupling capacitors. If the lowest signal frequency is 9kHz, use a 4.7µF capacitor in parallel with 100nF capacitor on each input-output pin. The device has a two-stage architecture and provides approximately 16dB of gain in single-ended-to-differential mode, when driving a differential 100Ω load for single-ended inputs driven from a 50Ω source. This device also works as a fully-differential amplifier.

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 TRF0208-SEP is powered with 3.3V supply. A power-down feature is also available.
