QPB2328 17.5 dB Balanced Return Path Amplifier 5210MHz Product Overview The QPB2328 is an HBT RF balanced amplifier IC operating as a return path amplifier capable of supporting DOCSIS 3.1 applications. This IC is designed to provide a low noise, high gain option for 5-210MHz interface using an 8V power supply to provide lower overall power dissipation. The QPB2328 can also be used in 5V and single ended Package: SOIC-8 with Exposed Pad applications with reduced linearity requirements. The QPB2328 is packaged in a convenient SOIC8 package and features an externally adjustable bias control.
