Modification of a 1,5GHz front-end to 1,3GHz

Typical data on 1,3GHz after modification :
Gain: 11-14dB, NF - 1,3dB
Active device is NEC NE-72084
Single rail supply.

This front end was originally made for 1,5GHz.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.
