Qorvo's TAT8858A1H is a cost effective 75 Ohm 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. This product 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. Please contact Qorvo for details.
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. Please contact Qorvo for further details.
Typical Applications
- 75 ohm Amplifier
