Ready to Use OEM 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.
