Ready to Use OEM Module

The DR3000 transceiver module is ideal for short-range wireless data applications where robust operation,

small size and low power consumption are required. The DR3000 utilizes RFM’s 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 includes the TR1000 plus all configuration com-

ponents in a ready-to-use PCB assembly, excellent for prototyping and intermediate volume production runs.
