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.
