General Description
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.
