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.
