RF2317
LINEAR CATV AMPLIFIER
• CATV Distribution Amplifiers
• Cable Modems
• Broadband Gain Blocks
• Laser Diode Driver
• Return Channel Amplifier
• Base Stations
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 75
Ω 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 75
Ω input and output impedances and
requires only two external DC biasing elements to oper-
ate as specified.
• DC to 3.0GHz Operation
• Internally Matched Input and Output
• 15dB Small Signal Gain
• 4.9dB Noise Figure
• +47dBm Output IP3
• Single 9V to 12V Power Supply
