alc circuit
hi,i am working on a WCDMA PA design,now i encount a problm about analog ALC.
the ALC circuit is comprised of two OP,which is integrated in LMC6482. the first OP is used to comprise a integral circuit as a comparisor,the second one is as a adder.
when i push the power to the ALC control point, the output power jump up and down, the more heigher i push ,the larger it jump, in a word ,it is not in a steady status ...the detector ic i choosed is AD8364 ,anybody could help me? pls help me analyse the problem,thanks.[/img]
