CPI LRKA2XXX-XXXXXXX

LRKA2XXX-XXXXXXX Ka-Band 1:2 Redundant LNA System 

The CPI LRKA-1000 Series 1:2 Ka-Band Redundant LNA System supports dual receive chains with a shared backup LNA for seamless failover. The system’s outdoor plate assembly integrates waveguide/coax switches and optional crossguide couplers and filters, while the rack-mounted indoor controller handles SNMP/serial/parallel M&C with fast fault detection and switchover. Selectable frequency bands include 18.2–20.2 GHz, 20.2–21.2 GHz, or 17.7–21.2 GHz. Designed for high-reliability SATCOM installations, the system maintains operational readiness even in harsh environments.
