RADIALL ‘LOW PIM’ INTRODUCTION

ConfidentialDec-13 3

Introduction : What is PIM ?

• The Passive Intermodulation (PIM) is a signal distortion that occurs whensignals at several frequencies are transmitted thru a passive device(connector, cable, switch, antennas…) which has some non-linearresponse. Then the fundamental frequencies will be distorted and series ofhigher order harmonic frequencies will appear in the frequency domain. Ifsome of these frequencies appear in the receive bands of a wireless systemit will raise the receiver noise floor and reduce the system performance.

• The main sources of intermodulation in wireless systems are the activedevices in transceivers and receivers but their intermodulation can bereduced or eliminated by filtering which is not possible for passive devicesinserted in transmission line. Therefore when intermodulation becomescritical for a system the only solution is to use Low PIM passive devices.

Introduction : How is PIM specified ?

• If we call F1 and F2 the fundamental frequencies (carrier frequencies), then thepossible PIM frequencies can be described as follow:

FPIM = n.F1 ± m.F2 n + m is the order of intermodulationFor example: 2F2-F1 (m=2 and n=1) or 2F1-F2 results to a 3rd order PIM product.

Introduction : How is PIM specified ?

• Usually odd PIM orders (3rd, 5th, 7th…orders) are the main concern becausetheir frequencies are close from the carrier frequency and may disturb thesystem behavior. As the strength of the signal decreases with the order ofPIM, the 3rd order is often the most critical and is the one usually tested andspecified by component manufacturers.

• PIM is specified in dBc and dBm terms: dBm is a measure of power relativeto 1mW and dBc is a measure of dB below a given carrier level. A typicalpower level in testing passive devices is +43dBm (20W). In that case if thePIM level is -110dBm, it is equivalent to a PIM level value of :

-110-43= -153dBc

A low PIM device has typically a PIM level of -150 to -160dBc

Introduction : Telecoms situation...

• Today there is a growing demand on wireless communication devices withhigher data rates. 4G or LTE (Long Term Evolution) is the fourth generationstandard for mobile phone and allows supplying speeds almost 10 times higherthan current networks and providing an answer to this frenetic growth of dataconsumption. The deployment of 4G networks is designed to cope with theexplosion of mobile use. Data volumes on the network operator Orange, forexample have been multiplied by 68 in 5 years and will still grow by a factor of 7by 2015...

• This exploding demand will request wireless and RF systems to be very reliableand to work with their full coverage capacity. Since Passive Intermodulationcould seriously impact these performances, the low PIM devices will be of highinterest for wireless and RF Test industry.
