What is Passive Intermodulation (PIM)

Passive Intermodulation (PIM) Passive Intermodulation (PIM)

TX signals at site

PIM = interference

PIM = new frequencies generated by Tx signals when they encounter

non-linear junctions or materials in the RF path

PIM falling in an uplink band can elevate the noise floor

Dropped calls Access failures Slower data rates

Downlink Uplink



What is a non-linear junction

Slide 4

bull Current increases linearly with applied voltage

bull High pressure metal-to-metal contacts

bull Welded or soldered connections C u r r e n t

Linear junctions

Non-Linear junctions

bull Current does not increase linearly with voltage

bull Low pressure metal-to-metal contacts

bull Oxide layers on metal surfaces

bull Arcing across small air gaps or cracks




What is non-linear in IBW networks

bull

Poor cable terminationbull Damaged poorly made components

bull High power RF terminations

bull Loose RF connections

bull Type-N connectors

What about TDD- LTE

Slide 16

Synchronized TDD

Un-synchronized TDD

bull TDD systems Tx and Rx are at diff erenttimes

bull PIM is only produced while transmitting

bull

PIM is only an issue for adjacent bands

bull Adjacent TDD bands should be

synchronized to prevent interference

How do we measure linearity

18

With a PIM tester

Inject two CW test signals at a known magnitude

Measure 3rd order intermodulation product (IM3)

IM3 ldquocharacterizesrdquo the linearity of the system

bull

If IM3 is low = linearity is good

bull

If IM3 is high = linearity is bad




What determines PIM severity to an IBW operator

1

Which IM product(s) fall in the uplink band

A

Low order IM products in uplink = higher uplink noise

B

More frequency bands operators = higher probability

of low order product in uplink band

2

Degree of non-linearity of PIM source A

More non-linear = higher PIM magnitude

3

Level of current flowing through non-linear junction material

A

Higher current = higher PIM magnitude

B

Higher RF power level = higher PIM magnitude

C

PIM source location orientation

D

PIM source distance from antenna

Is external PIM really a concern below 100 mW

bull External PIM measured while walking across office environment

bull 700 850 1900 amp 2600 MHz PIM test signals combined

bull Signi1047297cant PIM at low frequencies even with 15 dBm (32 mW) Tx power

Indoor antenna




How can I prevent PIM problems in IBW systems

1

Avoid frequency combinations that create low orderIM products in uplink bands

2

Use low PIM construction techniques materials

3

Avoid non-linear objects near antennas

1 and 3 above may be outside of your control

bull Multi-operator requirements

bull

Aesthetic requirements




Methods to mitigate external PIM1) Move the antenna

bull Non-linear objects in antenna near 1047297eld generate higher PIM

bull Moving antenna a short distance moves PIM source to far 1047297eld

bull At 20 dBm (100mW) PIM reduced gt60 dB when antenna moved 05m

Indoor antennaDiode

Near1047297eld

2) Move the PIM Source

bull Electrical conduit added after DAS was

installed and commissioned

bull Safety cables lightly touching metal

surfaces on near antenna




3) Add attenuation between antenna amp PIM sourcePIM source

PIM source covered with Aluminum duct tape

gt40 dB PIM reduction




4) Direct less power at PIM source

bull Antenna with ldquonotchrdquo in horizontal pattern

bull

Rotate antenna to steer null at PIM source

bull Up to 30 dB reduction in PIM

Summary

bull

bull

bull

Power levels in use

bull

PIM can be a problem even at very low power levels

bull

PIM can be mitigated by

bull

Eliminating ldquobadrdquo frequency combinations

bull

Using low PIM construction techniques materials

bull

Reducing RF energy arriving at the PIM source
