Module
The DR5103 receiver module is ideal for short-range wireless data applications where robust operation,
small size and low power consumption are required. The DR5103 utilizes RFM’s RX5003 amplifier-
sequenced hybrid (ASH) architecture to achieve this unique blend of characteristics. The receiver RX5003 is
sensitive and stable. A wide dynamic range log detector provides robust performance in the presence of on-
channel interference or noise. Two stages of SAW filtering provide excellent receiver out-of -band rejection.
The DR5103 includes the RX5003 plus all configuration components in a ready-to-use PCB assembly excel-
lent for prototyping and intermediate volume production runs.
