The TriQuint TAT8858 is a cost effective 75 ohm RFIC Amplifier designed for use in high gain 24 V 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 TAT8858 may be easily adjusted by varying external components, allowing for a family of push-pull hybrid solutions to be developed from a single RFIC. The TAT8858 provides integrated linearization to improve the 3rd order distortion performance.
The TAT8858 may be protected against transient surges with the TQP200002
and an output high pass filter network.
The TAT8858 supports traditional 24 V and 12 V supply voltages. Bias current may be adjusted to suit particular requirements with standard or active biasing approaches.
