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.
