Passive Intermodulation (PIM) testing


What is Passive Intermodulation (PIM)

• PIM = interference

• PIM = new frequencies generated by Tx signals at a cell site

when they encounter “non-linear” junctions in the RF path

• PIM falling in an operator’s uplink can elevate the noise

floor:

▪ Dropped calls ▪ Access failures ▪ Slower data rates

Passive Intermodulation (PIM) Passive Intermodulation (PIM)


What is non-linear at a cell site?

• Loose metal-to-metal contacts

– Poorly terminated RF connectors

– Metal flakes inside connectors

– Loose RF connectors

– Metal flashing on rooftops

– Loose rivets, screws, etc.

• Rusty / corroded surfaces

• Non-linear materials

– Nickel / Steel

– Ferrite

First Generation PIM Master

• Introduced PIM Master™ Dec. 2010

• Distance-to-PIM™ technology

• 43 to 46 dBm output power (20 to 40 W)

• Controlled using:

– BTS Master

– Cell Master

– Site Master

– Spectrum Master

Three models:

850 MHz, 900 MHz, 1900/2100 MHz


New Second Generation PIM Master

• World’s first:

– battery operated

– high power PIM analyzer

• Lightweight / small size

– one-half the weight

– one-forth the size

• 25 to 46 dBm (0.3 to 40

W)

• Distance-to-PIM™

• No external controller

required

Six models:

700 MHz (U/L), 850 MHz, 900 MHz

1800 MHz, 1900 MHz, 1900/2100 MHz, 2600 MHz


MW82119A – PIM testing at top of the tower

Remote Radio Head (RRH) sites

• Fiber & DC power to RF unit

• RF path is jumper cable + antenna

• PIM sources reduced, but not

eliminated

• Traditional test equipment not

useful:

– Heavy

– No AC power

• MW82119A is the solution:

– Light weight

– Battery operation

– Remote control option
