QPB7420
75ꢀΩ 20ꢀdB CATV Amplifier 47 – 1218ꢀMHz
®
Product Overview
The QPB7420 is a GaAs pHEMT single ended RF
amplifier IC featuring 20dB of flat gain and low noise.
This IC is designed to support Fiber to The Home
(FTTH) applications from 47 to 1218ꢀMHz using a
single 5ꢀV supply, or it can be used from 3ꢀV to 8ꢀV
depending on linearity requirements. QPB7420 offers
low noise and distortion plus high gain in a SOT-89
package for convenient layout and design in set top
and infrastructure projects for 75ꢀΩ CATV and satellite
applications.
