The TRF1305A2 is a very high performance, closed-loop, dual-channel RF amplifier that has an operational bandwidth from true-dc to > 5.8GHz. The device has excellent performance to drive high-speed, high-performance ADCs, such as the ADC12DJ5200RF and ADC32RF5x with a dc- or ac-coupled interface. The amplifier is optimized for use in RF, zero and complex IF, and high-speed time-domain applications. The device is optimized for performance in the fixed gain configuration. If lower gain is desired, use external resistors.

The TRF1305A2 features a VOCM pin that allows setting different output common-mode and input common-mode voltages; for example, level-shifting or for most IQ down-converter ADC-interface applications that have differing dc common-mode voltages. The TRF1305A2 also features a floating two-rail split or single-supply option, and a MODE pin that allows extending the input common-mode range closer to the supplies. The device also has a power-down feature to turn-off each channel individually.

The device uses TI’s proprietary advanced BiCMOS process and is available in a space-saving, 2.5mm × 3mm, 16-pin, WQFN-FCRLF package.
