PRODUCT DESCRIPTION
The AIT1005 PicoTunerTM is a complete integrated data tuner that includes all the necessary RF tuner front end circuitry for cable modem applications. The AIT1005 combines GaAs and Silicon CMOS technology - which include the up converter, down converter and dual synthesizer circuits - along with a SAW filter, VCO tuning circuits, and passive components, to facilitate a complete double conversion tuner architecture. The AIT1005 is offered in a 40 lead package and requires one +5V supply, plus a low-power +28V supply for varactor tuning. It is well suited for applications that require complete, low cost, small size, high performance RF modules.
