PRODUCT DESCRIPTION
The AIT1005 PicoTuner
TM
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.
