Example of a configuration
The following example of a configuration shows a setup with one RF680R reader, one power
splitter and two RF650A antennas.
Figure 10-2 Example of a configuration with an RF600 system with a power splitter
The link between the reader and the power splitter (3.2 dB attenuation) is via a cable 1 m in
length (0.5 dB cable attenuation). Cables with a length of 5 m (1.25 dB cable attenuation) are
used between the power splitter and the antennas.
To calculate the total attenuation made up of the cable attenuation and the attenuation of the
power splitter, the various attenuation values need to be added. For the configuration shown
above, the total attenuation is as follows:
0.5 dB + 3.2 dB + 1.25 dB = 4.95 dB
The total attenuation of 4.95 dB must be stored in the configuration of the reader as user-
defined cable attenuation. When using several different antennas, the antenna gain of the
antenna with the highest gain must be specified. This ensures that the maximum permitted
transmit power is not exceeded.
Note that when using different antenna cable lengths, the radiated power of the antenna with
the longer cable is lower.
