Intermodulation Characteristics (3G TS 25.101.7.8)
This section explains how to complete an intermodulation response rejection performance
test on your user equipment (UE). It includes a process definition, signal generator
configurations, test system connections, abbreviations, an example test procedure and
performance test record.
NOTE An external source capable of providing CW at an amplitude of
−
46 dBm
across a frequency range of 2100 MHz to 2180 MHz is required for IRR
performance testing.
Specification Definition
Intermodulation response rejection is a measure of the receiver’s ability to receive a
desired signal at its assigned channel frequency in the presence of two or more undesired
interferers which have a specific frequency relationship (i.e. third- or higher-order mixing
products within the frequency band of the desired channel) to the desired signal.

Performance Test Objective
The objective of this performance test is to determine the Intermodulation Response
Rejection (IRR) performance of your UE against limitations described in the 3GPP
W-CDMA RF specification (3G TS 25.101 V3.3).
Defining Measurement
The PASS/FAIL status of the DUT is determined by measuring Bit Error Ratio (BER) in
the presence of two specified, frequency-related interferers.
