FEATURES

DESCRIPTION

The ACU50752 is a Monolithic GaAs IC designed to perform

the upconverter functions in a double conversion tuner: gain

block, local oscillator and balanced mixer. The

specifications meet the requirements of CATV, TV and

Cable Modem applications. Supplied in a 16-lead SOIC

package and requiring only a single polarity 5 V supply (or

3.5 V, with slightly reduced performance), the IC is well

suited in situations where small size, low cost, low auxiliary

parts count and a no-compromise performance is important.

It provides tuner manufacturers the opportunity to reduce

cost by lowering the component count and decreasing the

amount of labor-intensive production alignment steps, while

significantly improving performance and reliability.
