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

CATV 75Ω Adjustable Low Gain (9–11dB) RF Amplifier
Typical Application Schematic, 47MHz – 1218MHz
Notes:
1. L1/L2 tunes input return loss (L2 helps tune low frequencies).
2. C1 and C3 are for DC blocking
3. L3/C4 tunes output return loss.
4. B1 is a broadband impedance choke for DC bias.
5. R1 and C2 are optional feedback that can be added to reduce to gain to as low as 7.5dB (typ. gain of 10.5dB with no feedback)
6. R2 is an optional pullup that can be added to adjust the bias current to trade off distortion for noise performance.
7. Typical performance reperesented is with no feedback or pullup/pulldown.

PCB Mounting Pattern
Notes:
1. Ground/thermal vias are critical for the proper performance of this device. Vias should use a .35ꢀmm (#80ꢀ/.0135’) diameter drill
and have a final, plated thru diameter of 0.25ꢀmm (0.010”).
2. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance.
3. RF trace width depends upon the PC board material and construction.
4. All dimensions are in millimeters (inches). Angles are in degrees.
