Adjust balun component values
|
|
|
|
|
|
Some of the components specified in the schematics were not at hand
|
|
in my lab and were thus replaced with similar parts. Furthermore, the
|
|
LED color was changed to ease visual identification:
|
|
|
|
Component Norminal Board 1 Board 2
|
|
--------------- --------------- --------------- -------------------
|
|
LED (D1) red red red-orange
|
|
C6/C7 0.82 pF 0.7 pF 0.9 pF
|
|
L2/L3 4.3 nH 4.7 nH 4.7 nH
|
|
|
|
The resulting spectrum should be examined to determine which variant
|
|
performs better. Note that the discrete balun circuit shall be
|
|
replaced with an integrated balun later on.
