1.4.1 Network interface module (NIM) for TV reception
Application diagram
Make a high performance active splitter in a NIM tuner
with BGU703x.
Nowadays more flexibility in design and more complicated
signal handling is required for a TV tuner. A front-end of
a TV signal receiver is no longer just a tuned receiver, but
has evolved into a RF Network Interface Module (NIM) with
tuned demodulators, active splitters and re-modulators. The
active splitter requires an LNA with excellent linearity. We
have developed a new series of LNA/ VGA MMICs (BGU703x)
designed specifically for high linearity (IP3O of 29 dBm) in low
noise applications like an active splitter in a NIM tuner.

Save energy with BF11x8
The BF11x8 series are small signal RF switching MOSFETs
which can be used for switching RF signals up to 1 GHz. With
the use of the BF11x8 series as a RF switch you can save a
considerable amount of energy. When a recording device
(DVD-R, HDD-R, VCR, DVR) is powered off people can remain
watching TV, although the antenna is looped via the recording
device. Without using BF11x8 the antenna signal is lost. At the
moment the power of the recording device is on, the BF11x8
is open, so the RF signal travels via the recording device to
the TV tuner. At the moment the power of the recording
device is completely off, the BF11x8 closes. This ensures that
the RF signal is looped through directly to the TV tuner and
that TV reception is guaranteed. Energy is saved because the
recording device can be powered off.
