CPI LRS1XXX-XXXXXXX 1:1 S-Band Redundant LNA System

CPI LRS1XXX-XXXXXXX 1:1 S-Band Redundant LNA System

The CPI LRS-1000 1:1 S-band redundant LNA system minimizes receiver downtime by automatically switching from the primary LNA to a dedicated standby LNA when a failure is detected. Covering 2100–2500 MHz, the system combines two CPI LSH-2000 Series low noise amplifiers, an outdoor plate assembly, an indoor redundancy controller and an interconnecting control cable.
