RDL2
UHF Multi Channel Wide Band FM Transceiver
RDL2 is a half-duplex multi channel wideband FM
transceiver in a BiM series footprint and operates
on 433.05-434.79MHz European SRD band.
This makes the RDL2 ideally suited to those low
power applications where low cost multi-channel
operation is required.
Figure 1: RDL2-433-32
The RDL2 is a half duplex radio transceiver module for use in high-speed bi-directional data transfer
applications at ranges up to 300metres. The small footprint of 23 x 33mm together with low power
requirements of <28mA @ 5V enable convenient PCB installation.
RDL2 allows operation on one of 5 pre-set frequencies in the 433MHz European licence exempt frequency
band. These frequencies are non-overlapping and simultaneous operation of RDL2s in the same area on
different channels will be possible. Units are supplied on 433.92MHz (Ch0) as default.
