Accessories:1090MHz 3 Pole Filter (Type 2)

1090MHz 3 Pole Filter Type 2
(both ports SMA female)

Passband measured on a R&S FSEA with tracking generator
Upper: wideband showing 10dB bandwidth/div
Lower: narrow band, high resolution, showing 3dB bandwidth}

This filter is a new development. There are three major changes in comparison to the filter described in External Filters

• The filter's passband is smaller than the previous 3 pole filter

• It has a massive DC short on the input and the output protecting the connected devices from static electricity and lightening (*1)

• The size is about half of the 3 pole filter of the first generation

• Technical data:
  • passband attenuation: 0.5 dB
  • -3 dB bandwidth: better than 9 MHz

• Options
  • Standard connectors are two SMA female connectors
  • The filter can made with N-female, N-male or BNC-female connectors each separately for both ends.
  • Both connectors can be placed on the same side
  • We can attach a massive M6 or M8 bolt on the side wall for a grounding strip

• Dimensions
  • Length approximately 112 mm
  • Width approximately 30 mm
  • Height approximately 70 mm plus length of connectors
  • Weight approximately 0,275 kg (SMA female connectors)

Note that due to the connector options there are small predrills visible on the optional connector locations.
