The device is manufactured on a Gallium Arsenide process and is featured in an SOP16 batwing package. It has been designed for use as an easily cascadable 75Ω gain block with a noise figure of less than 2dB. Gain flatness better than 0.5dB from 5MHz 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 frequency bands up to 2500MHz. The device is self-contained with 75Ω input and output impedances providing 2:1 VSWR matching. For higher input and output return losses, see the evaluation schematic.
