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 fabricated on an advanced Bi-CMOS process, and is housed in an eight-lead SOT23 package.
