inate Out-of-Band Interference at your C-Band Receive Antenna
● Low Insertion loss
● Low Group Delay Variation - Typically ≤ 8 ns (Ideal for Digital Applications)
● Economical Price
● Quick Delivery (Stock to 1 Week)
● Less Than 6 inches Long (Fits Under Standard Weather Housing)
● Available for all International bands.
● Also rejects transmit band (5.8 - 6.5 GHz) - eliminating the need for a separate transmit reject filter
With low insertion loss and minimal group delay variation, the series 7893D is ideal for digital applications.
The Series 7893D waveguide bandpass filter is installed between a TVRO feedhorn and the LNA or LNB to suppress strong out-of-band interference caused by marine or airport radar systems.Coastal and marine navigational radar frequencies (2.9-3.65 GHz) are just below the TVRO band and frequently wipe-out transponders 1-5 in TVRO’s installed near harbors. The airport altimeter band (4.25-4.40 GHz) will affect channels 22-24 at TVRO sites near airports. The series 7893D interference filter operates at RF, before block down conversion. This prevents the generation of undesirable mixer products and receiver “desensitization” due to strong out of band signals.
