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.

Application Note
Due to design characteristics of the CXE-2089Z Linear Gain Amplifier, improvements in multi-tone distortion performance will
be seen with increased operating current up to 130mA. Degradation in multi-tone distortion may be seen when operating at
current levels below 105mA.

Description
RF Input Pin. This pin requires the use of an external DC-blocking capacitor chosen for the frequency of operation.
Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads
as possible.
RF Output and bias pin. DC-voltage is present on this pin, therefore a DC-blocking capacitor is necessary for
proper operation.
