Technical information / Electrical features

In t e rm o d u la t io n p a ra m e t e rs

Base stations are using modulation signal thatTEMEX 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. 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

• 2. Forward intermodulation F1, P1, F2, P2, as input signals will give a forward

Intermodulation level IMP3

• 3. Reverse intermodulation F1, P1 in input, F2, P2 at the output, as input signals will

give a reverse intermodulation level IMP3

• 4. F1 and F2 are two tones with 20 MHz difference
