IF GAIN CONTROLLED AMPLIFIER
Typical Applications
• CATV Set-Top Boxes
• Cable Modems
• Cable-Ready TVs
Product Description
The RF3330 is a gain-controlled amplifier suitable for
application in the IF receive section of a cable tuner. It
consists of a high impedance differential input stage, a
low impedance differential output stage, and a differential
gain-controlled amplifier. The voltage gain may be varied
by applying an analog control voltage. The device is fabri-
cated on an advanced Bi-CMOS process, and is housed
in an eight-lead SOT23 package.
