Example of a configuration
The following example of a configuration shows a setup with one RF680R reader, one power splitter and two RF640A
antennas.
Figure 3-1
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). Between the power splitter and the antennas a cable with a length of 3 m (1 dB cable attenuation) and a cable
with a length of 5 m (1.25 dB cable attenuation) are used.
To calculate the total attenuation made up of the cable attenuation and the attenuation of the power splitter, the branch with
the lowest cable attenuation must be considered. For the configuration shown above, the total attenuation is as follows:
0.5 dB + 3.2 dB + 1 dB = 4.7 dB
The total attenuation of 4.7 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.
