CPI LRL2XXX-XXXXXXX 1:2 L-Band Redundant LNA System

CPI LRL2XXX-XXXXXXX 1:2 L-Band Redundant LNA System

The CPI LRL-1000 1:2 L-band redundant LNA system protects two receiver paths with one shared standby low noise amplifier. If either primary LNA fails, the controller automatically transfers the affected RF path to the standby unit, providing reliable and equipment-efficient redundancy for dual-channel L-band receiving systems.

Output P1dB: +8 dBm min., +11 dBm typ.
Optional High-Power Output: +18 dBm min., +19 dBm typ.
Input VSWR: 1.25:1 typ., 1.30:1 max.
Output VSWR: 1.20:1 typ., 1.25:1 max.
