DC to >7.2GHz, 10dB gain, fully-differential RF amplifier with common-mode control

The TRF1305B1 is a

very-high-performance, closed-loop, single-channel RF amplifier

that has an operational bandwidth from true-dc to > 7GHz. 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 TRF1305B1

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 TRF1305B1 also features a floating 2-rail split or single-supply option, and a MODE

pin that allows extending the input common-mode range closer to the supplies.

The TRF1305B1 has

a power-down feature. The device is fabricated with TI’s proprietary advanced BiCMOS process

and is available in a space-saving, 2mm × 2mm, 12‑pin, WQFN-FCRLF package.
