Block Up Converter S-band

Block Up Converter S band

 

 

Description and purpose:

 

A BUC is a Block Up Converter. The S band BUC gives 2200-2300 MHz output frequencies for 422 -522MHz input frequencies. Stability of the output frequency is important so the local oscillator is locked to an internal frequency reference.
