Product Description

The RF2318 is a broadband general purpose, low cost

high linearity RF amplifier IC. The device is manufactured

on an advanced Gallium Arsenide Heterojunction Bipolar

Transistor (HBT) process, and has been designed for use

as an easily cascadable 75Ω gain block. The gain flat-

ness of better than 1.0dB from 5MHz to 1000MHz, and

the high linearity, make this part ideal for cable TV appli-

cations. Other applications include IF and RF amplifica-

tion in wireless voice and data communication products

operating in frequency bands up to 5000MHz. The device

is self-contained with 75Ω input and output impedances,

and requires only two external DC biasing elements to

operate as specified.
