General Description

Pin Configuration

The TAT7430B is a low cost RF amplifier designed for

applications from DC to 1200 MHz. The balance of low

noise and distortion provides an ideal solution for a wide

range of broadband amplifiers used in cable television

applications.

It is particularly well suited for new home networks

requiring higher gain for a large number of splits. In

addition, the TAT7430B’s combination of high gain, low

noise, and good return loss make it an excellent choice for

optical receiver applications and low noise front ends.

An internal bias circuit mitigates the effect of temperature

and process variation. The bias current can be adjusted

with an external resistor. It is able to work in low noise

applications from a 5 V supply.

The TAT7430B is fabricated using 6-inch GaAs pHEMT

technology to optimize performance and cost. It provides

excellent gain and return loss consistency inherent to the

pHEMT process.
