Roofing Filters

Four types of roofing filters are equipped as standard as narrowband filters of high IP characteristics implemented by the 

full down-conversion method. In addition, to meet the needs for narrower band filters, optional filters are available (sold 

separately) and supported by a mounting slot. The “Photograph of Roofing Filters” is shown below:

Fig. 4  Photograph of the Roofing Filters

The filters of the 15 kHz, 6 kHz, 2.7 kHz, and 500 Hz (270 Hz) bandwidth are mounted from the top in the photograph. 

The filters of the 15 kHz and 6 kHz bandwidth are the 4-pole monolithic crystal filters (hereinafter referred to as MCF), 

and the filter of the 2.7 kHz bandwidth is the 6-pole MCF. The filter of the 500 Hz bandwidth is structured as the ladder 

type to suppress in-band insertion losses and to steeply shape the adjacent out-of-band attenuation characteristics. The 

ladder filter of the 270 Hz bandwidth, which is the much narrower band, is also available as an optional filter. For each 

ladder filter frequency response, the “Frequency Response of the 500 Hz Bandwidth” and “Frequency Response of the 

270 Hz Bandwidth” are shown below:

Fig. 5  Frequency response of 

 

the 500 Hz Bandwidth  

Fig. 6  Frequency response of 

 

the 270 Hz Bandwidth (Option)

The roofing filters for the receiver can be selected regardless of the operation mode.
In the RX Filter screen which appears on the display by pressing and holding the 

[IF FIL]

 key, switching to the roofing 

filter corresponding to the passband width can be used for the reduction of the interference signal.
