The Importance of Testing 600 and 1900 MHz Receiver Channels When Installing 600 MHz LTE Base Stations

In the 600 MHz spectrum plan, PIM issues are found in both the 600 MHz uplink and co-located PCS band at 1900 MHz. To ensure good network performance, operators or technicians must verify PIM performance at both the 600 and 1900 MHz uplink frequencies when transmitting two 600 MHz tones. Testing outlined in this document shows that mitigating PIM issue on 600 MHz band does not guarantee the same for the 1900 MHz band. Testing PIM at both frequency bands is imperative in order to mitigate PIM issues in the field. Doubling the test power from 20W to 40W improves measurement accuracy and provides a way to thoroughly test mobile communications systems and devices. When troubleshooting and PIM hunting, Anritsu’s PIM Master MW82119B analyzer with 40W capability provides more insight in to possible failure due to PIM at cell sites.
