Product Description
Broadband Gain Blocks
Laser Diode Driver
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 fea-
tured 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 flat-
ness 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 oper-
ating in the 50MHz to 1000MHz frequency range. The device is self-con-
tained with 75 input and output impedances providing less than 2:1
VSWR matching. For higher input and output return losses, see the evalu-
ation schematic.
