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 75
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 75
and requires only two external DC biasing elements to
operate as specified.
