Test Set Solutions Products

This product category contains specialized low-PIM filter-based offerings for 3GPP and LTE test sets and broadband emissions monitoring.

Types of products designed specifically to support 3GPP and LTE band emission monitoring include:

• Bandpass/Bandstop Duplexers
• Fixed Notch Filters (usually WSN prefix)
• Fixed Bandpass Filters (usually WSF prefix)
• Items covered in the DAS Brochure (see below)
• Certain Triplexers (usually WSD prefix)
• HI/LO Duplexers
• Bandreject/Bandpass/Bandpass Triplexers

Low-PIM levels offered are:

• -100 dBc
• "-1" level, or -133 dBc
• "-2" level, or -156 dBc
• "-3" level, or -161 dBc

This page will increasingly become a central location for presenting information on products of these types and levels, and our technical sales staff is ready to assist you, as always.

DAS Brochure - Low-PIM AMPS TX/RX Duplexers

DAS Brochure Newly Revised on 02/25/13.

K&L develops low-PIM filters for distributed antenna system (DAS) applications. Continued rollout of LTE requires low-PIM in order to maximize system performance. K&L’s DAS filter offerings achieve as much as -161 dBm to maximize system performance.

Covering Bands 5, 12-13, 2, and 10, respectively.

Low-PIM, High-Power - Filter Solutions for Monitoring Broadband Emissions

Enables monitoring of PIM to 13 GHz; 100W CW and 1KW peak

Near-end monitoring: Carriers rejected -90dB by the notch

travel through the bandpass filter to the low PIM termination.

Far-end monitoring: Carriers rejected -90dB by the highpass,

IM products passed are monitored by the spectrum analyzer.
