6 Detailed Description

6.1 Overview

The TRF1213 is a very high-performance, single-ended-to-differential RF amplifier optimized for radio frequency

(RF) and intermediate frequency (IF) applications with signal bandwidths up to 14GHz. The low frequency

response is limited only by the ac

‑coupling capacitor on the PCB. The device has flat pass-band response up

to 12GHz making this device an excellent choice for wideband applications, from HF to X band. The device is

designed for ac-coupled applications that require a single-ended-to-differential conversion when driving an RF

sampling analog-to-digital converter (ADC). The device has a two-stage architecture and provides approximately

14dB of gain when the single-ended input is driven by a 50Ω source.

This device does not require any pullup or pulldown components on the PCB, and thereby simplifies layout and

provides the highest performance over the entire bandwidth.

The input and output are ac coupled. The TRF1213 is powered with 5V supply. A power-down feature is also

available.
