TAT7430B
50 - 1000 MHz, 75 Ohm Single-Ended RF Amplifier
Qorvo's 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.
