Abstract
This article describes a stable phase-locked receiver configuration for tracking frequency ramp signals. A usual second-order receiver is used for lockup; subsequently a very simple modification is made to the loop filter, altering the loop to one of the third order. The altered loop then tracks the incoming signal with zero static phase error. The receiver bandwidth is practically unchanged; the damping factor lies in the region 0.5 and 0.707, and the design point is 12 dB in gain margin above instability.
