• 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

21. I International Workshop on Challenges and Trends Beyond LTE-A
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:
Three models:
850 MHz, 900 MHz, 1900/2100 MHz

24. I International Workshop on Challenges and Trends Beyond LTE-A
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
Six models:
700 MHz (U/L), 850 MHz, 900 MHz
1800 MHz, 1900 MHz, 1900/2100 MHz, 2600 MHz
• 25 to 46 dBm (0.3 to 40
W)
• Distance-to-PIM™
• No external controller
required

25. I International Workshop on Challenges and Trends Beyond LTE-A
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
