General Description
The TAT8857 is a cost effective 75 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 TAT8857 may be easily adjusted by varying
external components, allowing for a family of Doubler
solutions to be developed from a single RFIC.
The TAT8857 provides integrated linearization to improve
the 3rd order distortion performance.
The TAT8857 may be protected against transient surges
with the TQP200002 and an output high pass filter
network. Consult TriQuint for discussion.
The TAT8857 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.
