General Description
The TAT8858 is a cost effective 75 Ω 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. Consult TriQuint for discussion.
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.
Consult TriQuint for further discussion.
