IF Amplifier for Cable DVB Processing

Description

The U4459B is an integrated bipolar circuit suitable for The circuit contains a wideband IF amplifier, mixer stage,

the IF processing in cable-DVB receiver (DVB = Digital gain control for the IF amplifier and a tuner-AGC

Video Broadcasting) and cable network application.

(Automatic Gain Control) with adjustable take over point

for an additional external preamplifier (tuner).

Features
