QPQPB740B74000 CATV 75 Adjustable Low Gain (911dB) RF Amplifier Product Overview The QPB7400 is a low-cost RF amplifier designed for applications from 47 to 1218MHz. 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 QPB7400 has features allowing a great deal of design- 3-pin SOT-89 Package 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 Key Features external resistor may be used to adjust the bias current to optimize distortion or noise performance. Gain, return loss, and bias externally adjustable The QPB7400 is fabricated using 6-inch GaAs pHEMT 471218MHz bandwidth (DOCSIS 3.1 Compatible) technology to optimize performance and cost. It provides CCN65dBc, CSO70dBc, and CTB77dBc for excellent gain and return loss consistency inherent to the 33dBmV/ch at output (-6dB for QAM), 80 NTSC + 108 pHEMT process.
