Semtech Corp. (SMTC) is a fabless supplier of analog and mixed-signal semiconductor devices. Management has been diversifying the product portfolio, introducing new high-margin products and broadening the customer base.

July quarter results exceeded the consensus on both the top and bottom lines. Forward guidance is for 6-10% revenue increase in the October quarter.

Both revenue growth and margin expansion are expected to return in the second half of fiscal 2010 when the new product platforms gain traction. We are reiterating our BUY rating on SMTC shares.Zacks Investment Research
