DESCRIPTION
The ACU2110 is a CATV upconverter module, that when used with a synthesized downconverter, allows
integrating the tuner on the same PC board along with the rest of the electronics for data applications. These
applications included digital video, telephony, and cable modems. The module consists of a modified GaAs
upconverter, SAW filter, and varactor diode in a hermetic LCC package.
