CATV 75 Ohm pHEMT Adjustable Gain RF Amplifier

The TriQuint TAT7457 is a low cost RF amplifier designed for applications from DC to 2000 MHz. The balance of low noise and distortion provides an ideal solution for a wide range of broadband amplifiers used in cable television applications such as optical receivers and low noise front ends.

The TAT7457 has features allowing a great deal of design-in flexibility. Gain and return loss are adjustable with an external feedback resistor. An internal bias circuit mitigates the effect of temperature and process variation and an external resistor may be used to adjust the bias current to optimize distortion or noise performance. There are no on-chip capacitors limiting the low frequency response which extends down to DC.

The TAT7457 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.
