1 Scope
This International Standard refers specifically to the antennas and ancillary equipment used in
the mobile services.
This standard is intended to be used in conjunction with IEC 60489-1.
The supplementary terms and definitions and the conditions of measurement set forth in this
standard are intended for type tests and may also be used for acceptance tests.
2 Object
The object of this standard is to standardize the definitions, the conditions and the methods of
measurement used to ascertain the performance of antennas and ancillary equipment
(for example, duplexer) within the scope of this standard and to make possible a meaningful
comparison of the results of measurements made by different observers on different
equipment.

Add the following new clause 9 and new figures after subclause 8.4:
9 Measurement of duplexers
9.1 General
9.1.1 Supplementary terms and definitions
For the purposes of this standard, the following supplementary terms and definitions apply.

– 4 – 60489-8 Amend. 1  IEC:2000(E)
9.1.1.1
duplexer
device allowing the same antenna to be used for simultaneous transmission and reception
[IEV 712-06-16]
NOTE There are three terminals which are connected to the transmitter, the receiver and the antenna respectively
in a duplexer. The branch from the transmitting terminal to the terminal of the antenna is referred to as the
transmitting branch. The branch from the terminal of the antenna to the receiving terminal is referred to as the
receiving branch.
9.1.1.2
frequency stability (temperature)
drift characteristic of the extreme frequency at which the specified duplexer performance is
–6
satisfied, with temperature. It is expressed as parts per million per centigrade (10 /°C).
The duplexer performance (for example, transmitter noise suppression-ability, transmitter-to-
receiver isolation-ability, insertion loss and SWR) should be measured under the condition of
specified temperature range and more than specified frequency range
9.1.2
standard test condition
unless otherwise specified, all measurements should be performed under the general test
conditions as stated in IEC 60489-1 and the supplementary test conditions given below
9.1.3 Supplementary test conditions
9.1.3.1
test load
non-radiating load with an impedance and power rating specified by the duplexer manufacturer
9.1.3.2
connections to the measuring equipment
care must be taken to ensure that measuring equipment does not adversely affect the duplexer
loading conditions
9.2 Transmitter noise suppression-ability
9.2.1 Definition
The ability of the duplexer to suppress the transmitter noise on the frequency band of the
receiver, so a
