- Active power dissipation: 500 mW per channel
- Power-down for each channel
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 TI’s proprietary advanced BiCMOS process and is available in a space-saving, 2.5‑mm × 3.0‑mm, 16‑pin, WQFN-FCRLF package.
