6211LP/HP "Brickwall" Series
The
6211LP/HP series
of lowpass and highpass filter networks consist of channel deletion
filters and a custom-designed lowpass or highpass filter. This
combination results in a "brickwall" filter which eliminates
a block of channels while preserving the adjacent channel and
beyond. This allows the end-user to maximize CATV spectrum without
sacrificing any necessary channels. Two of the primary applications
for these models are: 1) Reinserting an alternate block of programming
within the deleted band…..and….. 2) Isolating one
portion of the CATV spectrum from another by diplexing a 6211LP
and a 6211HP between a common (3 dB) 2-way splitter.

3322 & 3378 Series
3322
lowpass filters
pass the segment of the TV spectrum below a prescribed cut-off
frequency.
The band segment above the cut-off frequency is suppressed. These
filters are AC/DC passing (500 mA Max).
3378 highpass filters pass frequencies above the cut-off frequency,
and suppress lower frequencies. Highpass filters are not AC/DC
passing.
Alternate "Cut-off Frequency" models are readily available upon request. |

10366 & 10365 Series
10366
Series filters isolate bands below the designated
cut-off frequency before they are combined for fiber runs. The
passband is defined as 50 MHz to any cut-off frequency up to 600
MHz.
10365 Series filters
isolate bands above the designated cut-off frequency before they
are combined for fiber runs. Passes from cut-off frequency (Fc)
to 750 MHz. |
