7)
Regulate the variable capacitors (3) and (4), related to the second amplifier so
as to diminish
Rej.Pwr
measured from the coupler.
8)
Regulate the variable capacitors (5) and (6), related to the third amplifier so as
to diminish
Rej.Pwr
measured from the coupler.
9)
Regulate the variable capacitors (7) and (8), related to the fourth amplifier so as
to diminish
Rej.Pwr
measured from the coupler.
10) Regulate the variable capacitors (9) and (10), related to the fifth amplifier so as
to diminish
Rej.Pwr
measured from the coupler.
11) Repeat the points from 6 to 10 until that the system power catches up a value
that cannot be diminished further.
Note:
•
The described procedure is adapted to the case tou want optimize the coupler
for a certain operating frequencies. When you may adjusted must itself be regulated
the coupler for the operation on whole band FM, carried out the regulations before
described to the frequency of 98.0 MHz, then repeated at 87.5 MHz and 108.0
MHz, until to finding the point of better compromise.
•
If the compensation comes made because an amplifier is been replaced, it is
generally necessary only to operate on the capacitors relative to the replaced
amplifier.
