Designed for Short-Range Wireless Data Communications
Supports 115.2 kbps Encoded Data Transmissions
3 V, Low Current Operation plus Sleep Mode
Ready to Use OEM Module
The DR3000-1 transceiver module is ideal for short-range wireless data applications where robust operation,
small size and low power consumption are required. The DR3000-1 utilizes RFM鈥檚 TR1000 amplifier-
sequenced hybrid (ASH) architecture to achieve this unique blend of characteristics. The receiver section of
the TR1000 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 transmitter employs SAW filtering to suppress output harmonics, facilitating compli-
ance with FCC 15.249 and similar regulations. The DR3000-1 includes the TR1000 plus most configuration
components in a ready-to-use PCB assembly, excellent for prototyping and intermediate volume production
runs.
