Designed for Short-Range Wireless Data Communications
Supports up to 115.2 kbps Encoded Data Transmissions
3 V, Low Current Operation plus Sleep Mode
Ready to Use OEM Module
The DR4103 transmitter module is ideal for short-range wireless data applications where robust operation,
small size and low power consumption are required. The DR4103 utilizes RFM’s TX5003 amplifier-
sequenced hybrid (ASH) architecture to achieve this unique blend of characteristics. The transmitter includes
provisions for on-off keyed (OOK) and ASK modulation. The transmitter employs SAW filtering to suppress
output harmonics, facilitating compliance with FCC 15.249 and similar regulations. The DR4103 includes the
TX5003 plus all configuration components in a ready-to-use PCB assembly, excellent for prototyping and
intermediate volume production runs.
