- 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.
