Designed for Short-Range Wireless Data Communications
Supports 2.4-19.2 kbps Encoded Data Transmissions
3 V, Low Current Operation plus Sleep Mode
Ready to Use OEM Module
The DR3100 transceiver module is ideal for short-range wireless data applications where robust
operation, small size and low power consumption are required. The DR3100 utilizes Murata’s
TR3000 amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of charac-
teristics. The receiver section of the TR3000 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 transmitter includes
provisions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The trans-
mitter employs SAW filtering to suppress output harmonics, facilitating compliance with ETSI
I-ETS 300 220 and similar regulations. The DR3100 includes the TR3000 plus all configuration
components in a ready-to-use PCB assembly, excellent for prototyping and intermediate volume
production runs.
