Low Noise Block Down Converter and Block Up Converter Filters Design for Ku Band

This paper presents a Ku band Low Noise Block Down Converter (LNB) and Block Up Converter (BUC) filters design. The LNB can convert Ku band signal (10.70 - 12.75GHz) to L band signal (950 - 2150MHz), equipped with gain control and mode control features whih is regulated by ARM based microcontroller. This LNB design achieved 55 dB conversion gain from the simulation that has been done. As for the BUC filters, three filters have been created with different requirement, there are L-band filter, Local Oscillator filter, and Ku band filter. And from the results of the experiment, these filters has VSWR value close to 1 with a range of band that fit to the requirement.
