3 LINEAR CATV AMPLIFIER
Typical Applications
• CATV Distribution Amplifiers
• Cable Modems
• Broadband Gain Blocks
• Laser Diode Driver
• Return Channel Amplifier
• Base Stations
Product Description
The RF2317 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 50MHz to 1000MHz, and the
high linearity, make this part ideal for cable TV applica-
tions. Other applications include IF and RF amplification
in wireless voice and data communication products oper-
ating in frequency bands up to 3GHz. The device is self-
contained with 75Ω input and output impedances and
requires only two external DC biasing elements to oper-
ate as specified.
