Test Set Solutions

This product category contains specialized low-PIM filter-based offerings for 3GPP/4G/5G 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

Please see the new main menu LTE Products navigation tab for Test Set Solutions by LTE Band. That will increasingly become a central location for presenting information on products of these types, and our technical sales staff is ready to assist you, as always.

K&L's most recent DAS Brochure is available for download in PDF format.

LTE/WiFi Test Box - Adjustable Bandwidth Tunable (700MHz - 6000MHz)

K&L has developed and is now shipping an LTE/WiFi testing solution digitally-controlled filtering system that can tune a bandpass filter anywhere in the 700 MHz to 6000 MHz range with continuously adjustable bandwidth. View latest video to see in operation.

MFA R&D Tunable - Adjustable Bandwidth Tunable (700MHz-1000MHz)

Allows passband centered at any frequency over tuning range while adding the capability to vary passband width. Upon input of desired frequency and bandwidth, tunes center frequency and adjusts bandwidth to provide a custom filtering solution on demand. Suitable for LTE and other test applications. The LTE/WiFi Test Box is the latest addition to this product family.

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.
