QPB7400

CATV 75Ω Adjustable Low Gain (9–11dB) RF Amplifier

Product Overview

The QPB7400 is a low-cost RF amplifier designed for

applications from 47 to 1218ꢀMHz. 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.

3-pin SOT-89 Package

The QPB7400 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.

Key Features

• Gain, return loss, and bias externally adjustable

• 47–1218ꢀMHz bandwidth (DOCSIS 3.1 Compatible)

• CCNꢀ–ꢀ65ꢀdBc, CSO–70ꢀdBc, and CTB–77ꢀdBc for

33ꢀdBmVꢀ/ꢀch at output (-6ꢀdB for QAM), 80 NTSC + 108

QAM, flat loading

The QPB7400 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.

• +5ꢀV Biasing, 105ꢀmA Current Consumption

• On-chip active bias for consistent bias current and

repeatable performance over temperature

• Low Noise: 3.5ꢀdB to 1218ꢀMHz

• +41ꢀdBm typical OIP3

• +60ꢀdBm typical OIP2
