For SwissFEL, two types of cavity BPMs are used. In the linac, injector and transfer lines, low-Q dual-resonator cavity BPMs with a loaded-Q factors (Q_L) of ~40 and 3.3GHz mode frequency allow easy separation of the two adjacent bunches with 28ns bunch spacing. For the undulators that receive only single bunches from a beam distribution kicker with 100Hz repetition rate, dualresonator BPM pickups with higher Q_L are used. The baseline version for the undulator BPMs is a stainless steel pickup with Q_L=200 and 3.3GHz frequency. In addition, an alternative version with copper resonators, Q_L=1000 and 4.8GHz frequency has been investigated. For all pickups, prototypes were built and tested. The status of pickup and electronics development as well as the latest prototype test results are reported.
