ad8302 phase
hi,
has anybody an idea how i can get out of the AD8302 a phase range from 0 to 360°?
in the datasheet they say.
"at higher frequencies, the finite rise and fall times of the amplitude limited inputs create an ambigious situation that leads to inaccessible dead zones at the 0° and 180° limits."
my idea was to use a branchline coupler to move the phase 90°.on each branch i put the AD8302.
do i need more than 1 coupler to get 360°?
is the pll important in this case?
thanks for help
