The TRF1305A1, TRF1305B1, and TRF1305C1 (TRF1305x1) devices are シングル チャネル, high-performance fully differential RF amplifiers optimized for very wideband signals from dc to > 6.5GHz. 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 TRF1305x1 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 amplifier allows the data converters to interface with a dc-coupled IQ demodulator or modulator if used in a direct conversion system. The TRF1305x1 family comes in three fixed power gain variants (15dB, 10dB, and 5dB), and has a closed-loop feedback-amplifier architecture.
The devices are powered using two-rail supplies with a typical differential voltage of 5V between the positive and negative supplies, and usable in split- or single-supply configurations. A power-down feature is also available that allows the amplifier to be powered down.
The output of the amplifiers is low impedance. Use appropriate external series termination to match to an arbitrary impedance.
