PRODUCT 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. Offered in a modified 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 for applications 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.
