TAT8857A1H
40 - 1000 MHz, 21 - 27 dB Gain CATV Infrastructure Power Doubler
Qorvo's TAT8857A1H is a cost effective 75 Ohm RFIC amplifier designed for use in doubler CATV applications up to 1000 MHz. It works with readily available SMT baluns and transformers to provide a highly flexible low cost replacement for traditional hybrids. Gain of the TAT8857A1H may be easily adjusted by varying external components, allowing for a family of doubler solutions to be developed from a single RFIC. This product provides integrated linearization to improve the 3rd order distortion performance.
The TAT8857A1H may be protected against transient surges with the TQP200002 and an output high pass filter network. Please contact Qorvo for details.
The TAT8857A1H supports traditional 24 V and 12 V supply voltages. Bias current may be adjusted to suit particular requirements with standard or active biasing approaches. Please contact Qorvo for further details.
