RDL2

UHF Multi Channel Wide Band FM Transceiver

Frequency:433.925 - 434.565 MHz

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.

The RDL2 modules are used 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.
