DR3100

433.92 MHz

Transceiver

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 RFM’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.
