Product details
The CPI DPXB8400N is a 400W X-Band outdoor SSPA in a NEMA 4X enclosure from CPI's DPXB8xxxN line. It delivers 400W saturated and 316W minimum at 1 dB compression across the 7.90–8.40 GHz X-band uplink.
Built on CPI's ModuMAX architecture with a field-replaceable RF assembly, it has 70 dB minimum gain with 20 dB of adjustment, an output isolator, a CPR-112G waveguide output and a 180–264 VAC power-factor-corrected supply drawing 2000W typically. The NEMA 4X enclosure mounts at the antenna hub or outdoors.
Order it as DPXB8400N-X; Option 7 adds an internal L-band block upconverter. The DPXB8xxxN Series comes in 2 listed models; compare them on the series page.
