70cm 430-440 MHz Filter | RTL-SDR

 

 

 
 

 

 
   

 

   

   

 

 
 

 

 
 

This filter will greatly improve the reception in this very popular band. It offers 40-50dB of attenuation for out of band signals. The filter will increase the S/N ratio and reduce potential interference. It uses one SAW component, measures only 50 x 10mm and features edge pads for easy soldering of a RF shield. Insertion loss is typically less than 2.0dB and LNA is not necessary.
