CXE-2089Z LINEAR GENERAL PURPOSE AMPLIFIER Package: SOT-89 Features 50MHz to 1000MHz Operation Internally Matched Input and Output 20dB Small Signal Gain 1.5dB Noise Figure +24dBm Output Power Single 5V to 9V Positive Power Supply Applications CATV Distribution Amplifiers Cable Modems Broadband Gain Blocks Laser Diode Driver Return Channel Amplifier Base Stations Functional Block Diagram Product Description The CXE-2089Z is a general purpose, low-cost, high-linearity RF amplifier IC. The device is manufactured on a Gallium Arsenide process and is featured in a small SOT-89 package. It has been designed for use as an easily cascadable 75 gain block with a noise figure of less than 2dB. Gain flatness better than 0.5dB from 50MHz to 1000MHz, and high linearity make this part ideal for cable TV applications. Other applications include IF and RF amplification in wireless voice and data communication products operating in the 50MHz to 1000MHz frequency range. The device is self-contained with 75 input and output impedances providing less than 2:1 VSWR matching. For higher input and output return losses, see the evaluation schematic.
