It is often desirable for operators of video links to utilise the spare bandwidth above the video band

to carry radio or telephony channels. These channels are modulated onto sub-carriers, often in pairs.

The filters offered in this range are for the separation of the sub-carrier channels from the video

band. They are designed on centre frequencies of 6.20, 6.80, 7.02, 7.50, 8.065, 8.59 and 10.70 MHz.

The passband and stopband widths are shown below. The group delay is approximately parabolic in

shape about the centre frequency.

Similar filters with other centre frequencies, bandwidths or impedances may be available on

request.
