Product details
The CPI SPXB8125N is a 125W X-Band outdoor SSPA in a NEMA 4X enclosure from CPI's SPXB8xxxN line. It delivers 125W saturated and 100W minimum at 1 dB compression across the 7.90–8.40 GHz X-band uplink.
Built on CPI's ModuMAX architecture with field-replaceable RF assemblies, it has 70 dB of gain with 20 dB of adjustment, a CPR-112G waveguide output, and a power-factor-corrected 90–135 VAC or 180–265 VAC supply drawing 1000W typ., 1300W max. The weatherproof NEMA 4X enclosure mounts at the antenna hub or outdoors.
Order it as SPXB8125N-X; Option 7 adds an internal L-band block upconverter. The SPXB8xxxN Series comes in 3 listed models; compare them on the series page.
