Product highlight:

Make a high-performance active splitter in a NIM tuner

with the BGU703x/ BGU704x

Today's TV tuners require complicated signal handling and benefit

from flexibility in design. The front-end of a TV signal receiver is

no longer just a tuned receiver, but has evolved into an RF network

interface module (NIM) with tuned demodulators, active splitters,

and remodulators. The active splitter requires an LNA with excellent

linearity. NXP has developed two new series of LNA/VGA MMICs

(BGU703x/BGU704x), designed especially for high linearity (P3O

of 29 dBm) in low-noise applications such as an active splitter in a

NIM tuner. The BGU703x family operates at a supply voltage of 5 V

and is intended for use with normal can tuners. The BGU704x family

operates at 3.3 V and works seamlessly with our Si tuner ICs, which

also operate at 3.3 V.
