Description
The AIT1000 PicoTuner^TM is a complete integrated data tuner that includes all the necessary circuitry for an
RF tuner front end for cable modem applications. The AIT1000 combines GaAs and Silicon CMOS technol-
ogy to provide an up converter, down converter, dual synthesizer, SAW filter, DC-DC converter, input filter,
tuning circuits, and all passive components to facilitate a complete Dual Conversion Tuner architecture.
The AIT1000 is supplied in a 40 lead package and requires a single +5v supply. It is well suited for
applications that require a low cost, small size complete RF tuner IC without compromising performance.
