QPB7400 – Amplifier
45-1218MHz 75 Ohm pHEMT – Adjustable Gain Amplifier.
The QPB7400 is a low cost RF amplifier designed for applications from 50 to 1218 MHz. The design 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-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.
Applications include Single-ended and Push-pull Optical Receivers, Low-noise Drop Amplifiers, Distribution Amplifiers, Multi-Dwelling Units, Single-ended Gain Block
