General Description
The TAT8858A1H is a cost effective 75 Ω RFIC
Amplifier designed for use in high gain 24 V or 12 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 TAT8858A1H 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 TAT8858A1H provides integrated linearization to
improve the 3rd order distortion performance.

The TAT8858A1H may be protected against ESD and
transient surges with the TQP200002 and an output filter
network. Consult TriQuint for discussion.
The TAT8858A1H supports traditional 24 V and 12 V
supply voltages. Bias current may be adjusted to suit
particular requirements with standard or active biasing
approaches. Consult TriQuint for further discussion.
