Product details
The CPI DPXB8350R is a 350W X-Band rack-mount SSPA from CPI's DPXB8350R line. It delivers 358W typical saturated (+55.5 dBm) and 305W minimum at 1 dB compression (+54.8 dBm) across the 7.90–8.40 GHz X-band uplink.
Built with technology from CPI's ModuMAX amplifiers, it has a modular architecture with 67 dB minimum gain, forward and reflected power monitoring, SNMP and HTTP network control, and integral 1:1 redundancy control. It runs on 90–135 or 180–270 VAC (1900W typical) in a 19 in, 8.75 in high chassis.
Order it as DPXB8350R.

Frequently asked questions
Can I set these up as a 1:1 or 1:2 redundant system?
Yes. Each SSPA has integral 1:1 redundancy control, and CPI builds 1:1 and 1:2 redundant systems around them. The RCP-2001 remote panel adds control from another location. Digisat can supply, install and commission the complete system.
How much rack space and power does it need?
It's a 19 in rack chassis, 8.75 in (222 mm) high and 27.88 in deep, weighing about 93 lb. It runs on 90–135 VAC or 180–270 VAC and draws about 1900W typically, up to 2100W at a cold start in saturation.
Need it installed, aligned or supported?
