The TRF1305B2 is a
very high performance, closed-loop, dual-channel RF amplifier that has an operational
bandwidth from true-dc to > 6.5 GHz. 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 preset gain configuration. If a lower-than-preset gain is desired,
use external resistors.
The TRF1305B2
features a VOCM pin that allows setting different output common-mode and input common-mode
voltages (for example, for level-shifting or for most IQ down-converter ADC-interface
applications that have differing dc common-mode voltages). The floating 2-rail split or
single-supply option, and a MODE pin that allows extending the input common-mode range
closer to the supplies. High channel-to-channel isolation allows the device to be used in a
complex IQ transmit or receive signal chain without loss of signal integrity.
The TRF1305B2 has
a feature to power down each channel individually. The device is fabricated in TIs
proprietary advanced BiCMOS process and is available in a space-saving, 2.5‑mm × 3.0‑mm,
16‑pin, WQFN-FCRLF package.
