LINEAR GENERAL PURPOSE AMPLIFIER

RoHS Compliant & Pb-Free Product

Typical Applications

• CATV Distribution Amplifiers

• Cable Modems

• Broadband Gain Blocks

• Laser Diode Driver

• Return Channel Amplifier

• Base Stations

Product Description

The RF2312 is a general purpose, low cost high linearity

RF amplifier IC. The device is manufactured on an

advanced Gallium Arsenide Heterojunction Bipolar Tran-

sistor (HBT) process, and has been designed for use as

an easily cascadable 75Ω gain block. The gain flatness of

better than 0.5dB from 5MHz to 1000MHz, and the high

linearity, make this part ideal for cable TV applications.

Other applications include IF and RF amplification in

wireless voice and data communication products operat-

ing in frequency bands up to 2500MHz. The device is

self-contained with 75Ω input and output impedances,

and requires only two external DC biasing elements to

operate as specified.
