Intermodulation parameters
Base stations are using modulation signal that TEMEX may not have.
In order to design and to provide data about intermodulation level 3, TEMEX is using a two tones
(channels) measurement.
The following conditions are used for the measurements:
• 1.
• 2.
• 3.
• 4.
Test set up
Power on each channel: defined by the customer or minimum 25 Watt if not specified.
Frequencies of each two tones: taken at the center of the bandwidth
Forward intermodulation F1, P1, F2, P2, as input signals will give a forward
Intermodulation level IMP3
Reverse intermodulation F1, P1 in input, F2, P2 at the output, as input signals will
give a reverse intermodulation level IMP3
F1 and F2 are two tones with 20 MHz difference
High band: 2090 MHz
