  In this paper, the design and the performance of two prototype detectors
based on Micromegas technology with a pad readout geometry is discussed. In
addition, two alternative implementations of a spark-resistent protection layer
on top of the readout pads have been tested to optimize the charge-up behavior
of the detector under high rates. The prototype detectors consist of 500 pads
with a size of 5x4 mm, each connected to one independent readout channel, and
cover an active area of 10x10 cm. The design of these prototypes and its
associated readout infrastructure was developed in such a way that it can be
easily adapted for large-size detector concepts.
