General Description
The TAT8857A1H is a cost effective 75 Ω 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.
The TAT8857A1H provides integrated linearization to
improve the 3^rd order distortion performance.
The TAT8857A1H may be protected against transient
surges with the TQP200002 and an output high pass
filter network. Consult TriQuint for discussion.
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. Consult TriQuint for further discussion.
