This paper will describe and analyze the rf beam position monitor (RFBPM) front- end upgrade for the Advanced Photon Source (APS) storage ring. This system is based on ampli- tude-to-phase (AM/PM) conversion monopulse receivers. The design and performance of the existing BPM front-end will be considered as the base-line design for the continuous effort to improve and upgrade the APS beam diagnostics. The upgrade involves redesigning the in-tunnel filter comparator units to improve insertion loss, return loss, and band-pass filter-matching that presently limit the different fill patterns used at APS.
