• Designed for Short-Range Wireless Data Communications

• Supports up to 19.2 kbps Encoded Data Transmissions

• 3 V, Low Current Operation plus Sleep Mode

• Ready to Use OEM Module

The DR5101 receiver module is ideal for short-range wireless data applications where robust operation, small

size and low power consumption are required. The DR5101 utilizes RFM’s RX5001 amplifier-sequenced

hybrid (ASH) architecture to achieve this unique blend of characteristics. The receiver RX5001 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

DR5101 includes the RX5001 plus all configuration components in a ready-to-use PCB assembly excellent

for prototyping and intermediate volume production runs.
