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.
