In addition to standard 1 and 2 m lengths, custom lengths are available.
Original Press Release:
QMA Cable Assembly with Verifiable Low PIM Performance for DAS Applications
LTE networks are more acute in decreased system performance due to interference caused by Passive Intermodulation (PIM) in Distributed Antenna Systems (DAS). Traditional cable assemblies with QMA connectors may be a source of PIM.
QMA connectors feature a snap lock connection as an alternative to threaded SMA connectors. QMA with excellent electrical performance up to 6 GHz is used in wireless infrastructure applications including DAS.
RF Industries manufactures cable assemblies using Times Microwave TFT-402-LF plenum rated, low loss, low PIM flexible cable terminated with QMA male straight or right angle connectors. The cable assemblies meet UL910 fire requirements for in building applications. PIM performance is less than  -140dBc using 2 tones at 20 watts. Less than -155dBc PIM performance is available on premium QMA straight assemblies.
All low PIM cable assemblies manufactured by RF Industries are tested to certify they meet or exceed the advertised specifications. The PIM value is printed on the cable assembly along with a serial number. For verification, a complete PIM performance chart is available for download by entering the cable serial number using PIM Tracker™ on the RF Industries web site.
Assemblies are available in standard 1 and 2 meter lengths as well as custom lengths. In addition to QMA connectors, the assemblies can be terminated with SMA, N, 7-16 DIN and 4.1-9.5 (Mini) DIN connectors.
