The DR3100-1 transceiver module is ideal for short-range wireless data applications where ro-
bust operation, small size and low power consumption are required. The DR3100-1 utilizes
RFM’s TR3000 amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of
characteristics. 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 transmit-
ter includes provisions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modula-
tion. The transmitter employs SAW filtering to suppress output harmonics, facilitating compliance
with ETSI I-ETS 300 220 and similar regulations. The DR3100-1 includes the TR3000 plus all
configuration components in a ready-to-use PCB assembly, excellent for prototyping and
intermediate volume production runs.
