Powerwave LGP twin dual-diplexer for 1800MHz
Powerwave Technologies was a US wireless infrastructure manufacturer, founded in 1985 and based in Santa Ana, California, that supplied base station antennas, tower mounted amplifiers, filters and RF combining/diplexing hardware. It grew through acquisition, including Sweden's LGP Allgon in 2004 — which is why some Powerwave-era part numbers, including this one, carry the legacy LGP prefix — along with wireless assets from REMEC and Filtronic. Powerwave filed for Chapter 11 bankruptcy protection in January 2013, converted to Chapter 7 liquidation in June 2013, and ceased operating; its patent portfolio was later acquired by Intel in 2014. CRS PLUS sources remaining Powerwave/LGP-branded units strictly as refurbished or used legacy stock — there is no current Powerwave entity, warranty, or manufacturer support channel for this equipment.
How to read these part numbers
The source description TwinDualDplx1800MHz FBand P identifies this as a twin dual-diplexer unit for the 1800MHz band, in Powerwave's F-band, P-series variant. The LGP prefix on the part number (LGP18521) marks it as originating from the legacy LGP Allgon product line that Powerwave acquired in 2004 and continued to sell under its own part numbering.

Ordering notes
Because Powerwave no longer exists as a company, there is no manufacturer validation, firmware update path or warranty available for this unit — we recommend a qualified RF engineer confirms fit-for-purpose against your current site design before ordering. Condition is stated per quotation; this is refurbished or used legacy stock, and availability is confirmed on enquiry. Hardware only: no software or licensing is associated with a passive diplexer of this type. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will confirm this on the quotation.
Lifecycle and availability
Powerwave Technologies ceased operating in 2013 — it filed for Chapter 11 bankruptcy protection in January and converted to Chapter 7 liquidation in June the same year — and its patent portfolio was later sold to Intel in 2014. The company no longer exists in any form and there is no current entity providing support, warranty, or replacement parts under the Powerwave or LGP name. The unit offered on this page is legacy refurbished or used stock only, sourced from secondary-market or decommissioned site inventory.

Questions
Frequently asked questions
Is Powerwave still a manufacturer?
No. Powerwave Technologies filed for Chapter 11 bankruptcy in January 2013, converted to Chapter 7 liquidation in June 2013, and ceased operating. Its patents were later sold to Intel in 2014. There is no current company providing support or warranty under the Powerwave name.
Why does the part number start with LGP?
LGP refers to LGP Allgon, a Swedish antenna and RF company Powerwave acquired in 2004. Powerwave continued to use the LGP part-numbering prefix on hardware descended from that acquisition, including this unit.
Can I get a warranty or firmware update for this unit?
No — since Powerwave no longer exists, this equipment is sold strictly as refurbished/used legacy stock with no manufacturer support channel. We recommend having a qualified RF engineer confirm fit-for-purpose before ordering.
