Modification of a 1,5GHz front-end to 1,3GHz Typical data on
1,3GHz after modification :
This front end was
originally made for 1,5GHz. The preamp has been cut out
from its original board. The VDD is in the range +5 to +10V.
Without further adjustment, the preamp performs well as a second stage
on 1G3. If you want to tweak out the last tenth of dB's of the preamp,
the input capacitor pad may be resized and the L
(one turn CU wire) adjusted.
