7.1 Overview

The TRF1305A2TRF1305B2TRF1305C2 (TRF1305x2) devices are dual-channel, high-performance fully differential amplifiers optimized for very wideband signals from dc to > 6.5 GHz. This device family is primarily designed to interface with high-speed and RF data converters that often require differential input (ADCs) and output (DACs) signaling. The TRF1305x2 can be dc or ac coupled, and configured as single-ended input and differential output (S2D) or differential input and differential output (D2D). The devices feature an output common-mode pin (VOCM) that allows the flexibility to set a desired common-mode output voltage. The VOCM pin sets the same output common-mode voltage for both shared channels. The amplifier allows the data converters to interface with a dc-coupled IQ demodulator or modulator if used in a direct conversion system. The TRF1305x2 family comes in three preset power gain variants (15 dB, 10 dB, and 5 dB), and has a closed-loop feedback-amplifier architecture.

The devices are powered using two-rail supplies with a typical differential voltage of 5 V between the positive and negative supplies, and usable in split- or single-supply configurations. A power-down feature is also available that allows each amplifier channel to be powered down individually.

The output of the amplifiers is low impedance. Appropriate external series termination can be used to match to an arbitrary impedance.
