Bandpass Filter suits multifeed applications.
Electronic Components & Devices

Bandpass Filter suits multifeed applications.

Model 13961 low-profile, waveguide bandpass filter is installed between LNA or LNB and feedhorn to suppress strong out-of-band terrestrial interference. Since unit does filtering at C-band frequencies, LNA and LNB overload is prevented and overall picture quality is improved. Filter is fully compatible with digital systems, providing low differential group delay characteristics typically less...

Electronic Components & Devices

C-Band TVRO Interference Filter suits digital applications.

Model 7893D bandpass filter offers insertion loss of less than 0.4 dB (center) for 3.7 to 4.2 GHz receive band. Rejection of 25 dB minimum at 3.65 and 4.25 GHz provides suppression of marine and altimeter interference frequencies. Unit also provides 75+ dB rejection at 3.5 and 4.4 GHz. Group delay of less than 8 nS suits digital applications, and LNA and LNB overload is prevented. Constructed...

Bandstop Filter is for Ku-band.
Electronic Components & Devices

Bandstop Filter is for Ku-band.

Model 14560 passes satellite downlink signal from 10.95-12.75 GHz with less than 0.1 dB insertion loss. Lightweight aluminum filter provides greater than 70 dB attenuation to unwanted uplink signal from 14.0-14.5 GHz. Return loss is greater than 20 dB across entire downlink spectrum. Military-grade plating permits electrical characteristics to be maintained over broad range of field operating and...
